ICS was the start for converging tablets, smartphones, and any Android-run device into one OS. So every new iteration of Android from here on out should be for all Android devices.
This.
I have a strange feeling that windows 8 is gonna suck. Google has nothing to worry about right now. ICS is amazing
I dont think Google is worrying, but not because of Windows being a threat.
I kind of wonder if the whole "Dual booting windows and android" thing is a tablet partnership with Microsoft? If you think about it, it's a win/win. android sells tablets that has both their own os on it and windows 8, which would dramatically increase the marketshare of android tablets, especially in the corporate world, and would bring android tablet sales back into the race with the iPad. Meanwhile Microsoft, which has never really had a foothold in the tablet world at all, would get a huge helping introduction in the tablet market decreasing the chances of their project crashing and burning in the first year.
I dont know about you guys, but I'd much rather use a Windows based tablet in my windows-based company environment than an iPad. Same platform = better compatibility (in theory at least.) I can only really see good in this if it's a partnership.
