Jason Langridge has done a great preview of Microsoft's upgrade of Windows Mobile. He has looked at the 1000+ upgrades to Windows Mobile 5 and as a a Senior Manager within the UK he has been using it for the last year.
Have Microsoft finally managed to develop an OS that gives mobile users something more than voice and texts? Rather than the X series from 3 this might be a platform the gives form to the hopes of the Mobile Web 2.0 fanboys.
On the screenshots it looks like the PIM functions are exceptional and the other office and surfing elements might mean that finally a single device is all that is needed. I guess the proof will be that they have removed the reset button seen on the iPAQ.
Guess the Microsoft briefing might be worth seeing next week in Barcelona.
