Well..
The microsoft surface looks interesting.. the case doubles as a keyboard. that's pretty cool. Is it going to kill the ipad? i doubt it. I also think its going to have a hard time fighting Android.. cause Android is open source.. companies will really want to use it..
like that company that is valued at over $1 billion... they have their own linux version.. I can't recall its name right now....
Windows 8.. imo.. really only good for ultrabooks, laptops, and desktops or, "laptops replacements." windows is a big massive system.. without some serious power, the tablets will be very busy keeping the os running...
but.. we will see I guess..
