WMExperts has a story about the specs for the new Windows 7 Chassis 1, a technical spec or baseline upon which hardware makers will base their first Windows 7 phones. Take a close look at this list and see if anything jumps out at you.

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.
