Engadget had a hands on with it on their sitre over the weekend. They found the tablets to be unresposive and slow. They say that the final release could be better though....
You can see how craptastic the software is in the video. Could they pull it all together before it ships? Sure? Will they? VERY doubtful. The software you see there is not close but with a few rough edges, it shows a very fundamental misunderstanding of what makes a good UI, they clearly don't "get it" yet. I'll believe they get 10 hours of battery when I see it, too.
This endless parade of janky junkware trying to mimitate the iPad is going to be fun to watch.
