It ws petty funky, but it is not a work tool that could replace my TT3. Way to difficult to launch aps, way to laggish at times, was too bad integration of programs(I didnt find the emal client e.g., or a way to beam a program, or ...)
And if you total up the market share of all these Windows devices, do they come close to the Treo for smartphones or Palm for handhelds?

Microsoft now has a much better PDA OS than Palm and Microsoft is actually working better with other companies and encouraging them to produce PDAs and smartphones that run WM.
