YUSSSSSSSS. Largely this thing is great. You hate comparisons, but I'm going to make them: It's not on par with the iPad (even the original version, to say nothing of the iPad 2.) There are simply too many things that don't work as they should. But it's already far more usable than any Android tablet I've encountered. By the time Microsoft gets ARM straightened out and can ship this OS on optimized hardware, it's going to really sing. This is, in fact, the first tablet other than an iPad I can see myself buying and using. It's early, but Microsoft seems to have a hit.
"Microsoft said we can't say who made the tablet until after today's keynote. (Damn, son.) But okay. That's cool. We won't mention which Korean manufacturer (that also makes lots of phones, some Android tablets, displays, televisions, and blu-ray players and is not LG or HTC) made this device until we get the official go-ahead."
Engadget supposedly has something about this also. I don't have the link, but from the comments I've seen in other discussions, this is basically the same full fledged tablet that hasn't sold for 10 years, complete with fan and 50% heavier than an iPad.
Something tells me this won't be an iPad killer...
