Very interesting. Nice to see a first glimpse of the OS I guess.
Lots of people saying about hardware restrictions, But the guys here know how to overcome such things. at the end of the day it'll be down to Driver support for devices rather than CPU speed, after all this thing isn;t doing anything different to 3rd party Apps like Pointui and Touchxperience, in fact it's probably doing less, so I don;t believe the hardware will be a problem.
I was reading on the Register that MS only started seriously developing WinPhos a year ago! that means it's probably very similar underneath to 6.5, by that I mean the general structure of the OS not the OS itself.
I can see MS coming down hard on XDA for trying to crack the OS when we finally get a ROM dump, as they seem to be really restricting this time around. They will probably give the guys here a years worth of unhindered OS cracking (jailbreaking) just so they can get some free debugging, then they'll stamp their foot down hard.
Waiting for a WInPhoS ROM for my Touch HD (LOL!)
