I'm definitely interested. The 7" form factor is great and it's from Google itself. My current 7-incher of an Android tablet is less than a year old but blown away by this machine. The 10 hr battery life promised by Google is going to be a real boon for those trans-Pacific flights!
I must say, this is probably the first time in quite a while Apple has reacted to a new product.. I think it's a nice device, I wish it had HDMI although some sort of DLNA streaming app will suffice.
The tablet for Windows 8 later this year will be better. It comes with an expendable keyboard. You can also run windows and office, along with the tablet experience.
This certainly will kill playbook. I simply do not see how they can remotely compete with Googles SW development pace. Since playbook has been release Goog has come up with about 3 revisions of Android.
