Microsoft on the way to make future MICROSOFT MOBILE!!

Sony Ericsson's Xperia X1 is at the high end of Windows Mobile phones.

You want a phone that can do it all? Internet, music, photos, films, documents, texting, instant messaging, diary, contacts and ... err ... phone calls?

Then a smartphone is right for you. But as the market for high-end mobiles gets ever more crowded, which should you pick?

The global market leader, Symbian, makes the software that runs most of Nokia's smart phones (and a few others).

Research in Motion with its e-mail friendly Blackberry devices has cornered the corporate market and is pushing into the consumer space.

Apple is minting it with its sleek but expensive iPhone. And only a few months ago internet search giant Google entered the field with its Linux-based Android software, designed to power internet-savvy mobile phones.

Oh, and then there is Microsoft. For years the giant of desktop computing has tried to push into the mobile phone market - not without success, but ultimately remaining a niche player.

Two things held Microsoft back in the past: technology and usability.

For years mobile phone technology simply wasn't advanced enough to play to the strengths of devices that were actually mini computers.

Windows Mobile and other smartphones were held back because they had to "live with the hardware capabilities of the past; key pieces were missing," says Andy Lees, the boss of Microsoft's Mobile Communications group.
