Having the latest and greatest Windows phones will no longer matter once Microsoft releases its Windows Phone 7 Series. Mobile-phone users running the latest Windows Mobile 6.5 operating system, made available in October, will have incremental upgrades but will need a new phone if they want to use the software giant's Windows Phone 7 mobile operating system.

Mobile-phone users with the latest Windows Mobile phones do not have the hardware needed to run the newest mobile operating system, according to Microsoft's Mobile Communication Business.

Users of both the iPhone and Android platforms are avid application users, but iPhone owners buy more apps. That's one of several conclusions about mobile users in the January 2010 Mobile Metrics Report from AdMob.

The mobile advertising network found that Android and iPhone consumers download approximately the same number of apps, and spend about the same amount of time using them. But about 50 percent of iPhone users buy at least one app per month, while only 21 percent of Android users do.

'Sheer Quantity and Variety'

The era of the PC's dominance is officially over. We have crossed over into the age of mobile computing.

This transition has been building momentum for a while. Some might argue that the iPhone was the dawn of this era. Others might say it was really the rise of the BlackBerry. Or maybe even Android, Google's mobile operating system. Good cases could be made that any one of these marked the start of the mobile era.

If you've got a car and a bicycle, do you need a motorcycle too? Wireless carriers are betting that you do. They're making a big push this year for the motorcycles of the gadget world: devices that are bigger than a phone but smaller than a laptop.

The most famous entrant in the category is Apple Inc.'s iPad, which comes out next month. But many other manufacturers are crowding into the niche, and were planning to do so even before Apple's announcement in January.

Sony Ericsson, a big but struggling maker of phones internationally, wants to be more than a bit player in the U.S. It plans to get there by giving U.S. consumers what they want: phones similar to the iPhone.

The strategy is much like the comeback recipe of U.S.-based Motorola Inc., which has hit on hard times since its Razr phone fell from popularity. It's revamping itself as a maker of smart phones running Google Inc.'s Android software.

With only a slight nod toward business clients during the launch of Microsoft's latest mobile-phone operating system this week, CEO Steve Ballmer fueled speculation that the software giant wants a bigger slice of the consumer pie.

Samsung Electronics Co., the largest maker of cell phones for the U.S. market, on Sunday revealed the first phone running Samsung's own "smart" software system, bada.

With bada, Korea-based Samsung is taking the TouchWiz system used on its touch-screen non-smart phones and making it the basis of a smart phone platform to take on Apple Inc.'s iPhone and Research In Motion Ltd.'s BlackBerry. Samsung also makes phones based on other competing smart phone systems: Android, created by Google Inc., and Symbian, of which Nokia Corp. is a major backer.

The world's largest wireless carriers, including the four largest in the U.S., announced Monday that they are combining forces to make it easier for software developers to write applications that will run on as many phones as possible.

The "Wholesale Applications Community" is an attempt to retake the initiative from phone makers like Apple Inc., Nokia Corp. and Research in Motion Ltd., which have applications stores of their own. Google Inc. is also building a significant store for its Android software.

Verizon Wireless will let customers use the Internet phone service Skype to make free calls on some phones, an application that wireless carriers have been slow to allow.

For months, mobile-phone users have heard rumors that Windows Mobile 7 might be delayed. However, Microsoft's mobile operating system may be in the hands of users sooner than expected.

Industry observers expect the software giant to introduce the updated platform next month at the Mobile World Congress in Barcelona, which is where the company launched its latest version, Windows Mobile 6.5.
