Think about this. The new Win­dows 7 hard­ware is going to require mul­ti­touch. This means it’s going to require capac­i­tive touch­screens, dif­fer­ent hard­ware from the cur­rent resis­tive touch­screens that itself requires a com­pletely dif­fer­ent, finger-​friendly user inter­face. A sty­lus will be use­less on these devices, which means none (or most) of your exist­ing soft­ware won’t work.

We can see from this spec list that Win­dows 7 will be a clean break from pre­vi­ous ver­sions of Win­dows Mobile, even from 6.5, which itself requires users to buy new hard­ware if they want the OS. (Though it’s more than capa­ble of run­ning 6.5 my Sprint Touch Pro isn’t eli­gi­ble for the upgrade. Why? Because the home but­ton is a lit­tle house rather than a Win­dows flag and Microsoft man­dates a Win­dows flag home but­ton on all 6.5 devices.)

New hard­ware. New OS. New soft­ware. And you need to wait until mid to late 2010 to get it. If you’re going to deal with all that change any­way, are you really going to wait for Win­dows Mobile?

I didn’t. I bought an iPhone.
