Apple Watch sells out almost instantly

Ship dates quickly stretch to June for the new wearable

The Apple Watch sold out almost immediately earlier today, making good on a promise by the company's head of retail that supply would not be sufficient at the start.

Ship times for the low-end Sport and mid-range Watch editions shifted to between four and six weeks within minutes of pre-order opening. Several hours later, all Sport models slipped straight to simply "June," the wide window that the highest-priced wearable, the 18-karat Edition, also showed as a delivery date.
Apple Watch order

Supplies of the Apple Watch sold out almost immediately Friday, with this order -- placed just two minutes after the online store opened -- showing delivery between five and seven weeks from today.

One Computerworld staffer processed an online order just minutes after the Apple online store opened at 12:01 a.m. PT (3:01 a.m. ET), and was told that the Sport model would be delivered between May 13 and May 27.

As is often the case on the first day of sales of a new Apple product, the Cupertino, Calif. company's online store was not rendering in a browser earlier today, likely because of large numbers of customers trying to get in all at once. The Computerworld staffer used the iOS Apple Store app on an iPhone to place the order.

It was impossible to say whether the long lead times were the result of an extremely short supply or an impressive number of orders. Apple may provide more information at its quarterly earnings call with Wall Street on April 27.

Angela Ahrendts, chief of Apple's retail and online sales, said yesterday that supplies would be tight, but spun that as indicative of wide interest as well as small inventories. "We expect that strong customer demand will exceed our supply at launch," Ahrendts said, marking the first time the firm has announced in a press release before a product launch that supplies would fall short.

Apple Watch orders are being taken only online, another unprecedented move by the company. Customers who want to actually try on a Watch -- not just look at them under glass -- must make appointments at an Apple retail store. As reported earlier, those appointments are in 15-min. increments, the time allowed by Apple for a fitting and a quick explanation of the device's features and functions.

Why Google wants to replace Gmail
Apple will begin selling the Watch in its stores on April 24, also the earliest delivery date for those who jumped on an online order straight away.

Almost lost in the hubbub about the Watch, the 12-in. Retina-equipped MacBook also went on sale today. The minimalist laptop starts at $1,299 and, in another first, comes in the same three tints as the iPhone and iPad.

The silver and space-gray models of the MacBook showed ship dates of between one and three business days, but the gold-colored laptop was delayed three to four weeks.

7 critical things to cover in your disaster-recovery plan

As always, you never know when a disaster will strike, so better to have a checklist on hand so that panic doesn’t set in when the network goes down.

1. Creating a plan
Cloud services company Evolve IP has created a list of suggestions for executives to evaluate their current disaster avoidance plans or, should a plan not exist, provide directional measures to protect their information and communications systems.

2. Establish a disaster recovery functional team
Elect one spokesperson from the group for communication. In the event of a multi-location organization each location should have a core team or representative that works with the corporate entity.

3. Risk assessment
Identify risks in the following areas:

Information – What information and information systems are most vital to continue to run the business at an acceptable level?

Communication Infrastructure – What communications (email, toll free lines, call centers, VPNs, Terminal Services) are most vital to continue to run the business at an acceptable level?

Access and Authorization – Who needs to access the above systems and in what secure manner (VPN, SSL, DR Site) in the event of a disaster?

Physical Work Environment – What is necessary to conduct business in an emergency should the affected location not be available?

Internal and External Communication – Who do we need to contact in the event of an emergency and with what information?

4. Cloud-based data centers and applications
Create a written recovery plan that is hosted remotely in a secure and redundant data center. Schedule and test your plan at least once per year or in accordance with regulatory/compliance requirements. Ensure employees can access the hosted environment (both from within the business confines and remotely) during fail-over mode from the designated locations.

5. Premise-based data centers
Produce a written recovery plan that is stored remotely. Identify water entry areas throughout the building and have sandbags available. Install VESDA smoke detection and thermal detectors. Have a fail-safe alarm system. Place high-temperature sensors on fire sprinkler heads if non-water based fire-suppression is unavailable. Keep your data center above street level. If you are in a single-floor building, raise your racks from the floor. Employ multiple Internet service/data providers and test for failover regularly.

6. Data back-up
Tape back-ups should be removed daily and stored in a secure, easily accessed public building with at least 2-3 individuals having keys to the location. Back-up data to a geographically distant location, either electronically, or ensure physical media is in a diverse location.

7. Hosted telephony systems
Employ multiple Internet providers and test for failover regularly. Verify that critical phone numbers have the ability to call forward in an unreachable condition.

8. Call center
Identify key business applications required and how call center staff will access these applications from alternative locations. Identify critical call types that must be answered and determine mechanism to segregate those calls. Identify alternative locations to house the staff with the appropriate systems, phones, and work environment. Ensure administrative staff has the ability to remotely change call routing, messaging, and related call center functionality.

10 new features expected in Windows 10

Later this week, Microsoft is expected to reveal more details about Windows 10. But why wait for Microsoft’s announcement? Here’s what we think is coming.

New features
Later this week, Microsoft is expected to reveal more details about Windows 10. We’ve already covered some of the major new features that are in the works, such as the return of the classic Start menu UI, resizable Windows apps, the ability to launch separate instances of the desktop environment and the inclusion of Microsoft’s personal digital assistant called Cortana. But why wait for Microsoft’s announcement? Here’s what we think is coming.

PC Settings replaces Control Panel
One of the confusing things about Windows 8 for desktop users is its “PC Settings” screen, because it includes a number of settings that can also be found in the classic Control Panel. In Windows 10, more of the Control Panel settings will probably be replicated under PC Settings.

Battery Saver setting
This setting will automatically take steps to conserve the battery of your notebook or tablet when it hits a certain percentage of remaining power. We wonder if its final version will be more sophisticated than what has shown up in the Windows 10 Technical Preview versions thus far. It would make sense if it looked similar to Windows Phone 8.1’s, which shows through bars and charts the amount of power that each program uses on your device.

Customizable lock screens
Some evidence in the Windows 10 Technical Preview suggests developers may be able to make custom lock screens. This could be similar to the way lock screens can be customized in Windows Phone 8.1.

Touch targeting
Touch targeting could be implemented throughout the Windows 10 UI. The basic idea is that the design will have icons, menus, and gesture functions tuned to be more responsive for touchscreens. The UI would adjust itself automatically based on whether you are using a mouse or a touchscreen.

Continuum
This looks to be a buzzword Microsoft came up with to market Windows 10’s ability to automatically switch between its two UI modes by recognizing if you are using your device as a notebook or tablet. For example, when you attach a keyboard to a tablet, Windows 10 will switch to the desktop environment. When you remove the keyboard, the OS returns to the tile-based Modern UI.

Updated File Explorer
It’s been hinted that the Windows file manager will get an update. Most likely, the new File Explorer will incorporate touch targeting to make it more accessible for touchscreens, but we’d like to see some new functionality that would benefit its desktop OS use, too: How about allowing for multiple instances of File Explorer to be opened as tabs within the program?

New security measures
There are going to be stronger security options, including two-factor authentication where you can use a device, like a smartphone, to authorize signing into your Windows 10 user account. Also, user access tokens could be stored in a secure "container" to protect them from exposure to hackers. Other measures are aimed at the business environment: users' personal and work files kept separate from one another; and restricting employees from installing programs that haven’t been digitally signed.

New updating methods
Multiple options will give businesses more control over how they want to update their Windows 10 systems: high priority updates that brings bug fixes and security improvements; updates that add new features to Windows 10; and a third option which lets administrators schedule when they want new features to be installed on their Windows 10 systems.

New animations
Besides refreshed icon designs and background wallpaper that you expect to see in any OS release, there will be new animated effects when you interact with Windows 10, such as a window expanding or shrinking when you launch or close an application. A lingering question has been if the classic Aero theme in an updated form, or other such transparency effects, will return.

Spartan
Lastly, one of the biggies is a brand-new web browser. Appropriately named Spartan, it’s speculated that it will take design inspiration from Google’s Chrome, with emphasis on a minimal UI and performance speed. Internet Explorer will still be available in Windows 10 to ensure compatibility with sites and enterprise services that require this browser, but it looks like Microsoft wants to start moving away from IE (and its less-than-stellar reputation) and have a fresh start with the everyday user in the browser market.
