Even with revisions I kind of want this product to fail. I recently purchased a nexus 7 which is a fantastic tablet but the earlier prototype had an sd slot and hdmi port. I suspect as others do, these features were taken out not as a cost cutting measure, but to steer you towards the Q.
If users have a nexus 7 with hdmi out most would say good enough and be happy with that. The nexus Q has more ports for audiophiles but the vast majority will be happy simply using hdmi to the hd display and then to whatever audio system they have for that.
And with hdmi, I could browse the web on a large screen, run games, apps etc. With this it's just stream content from your play purchases (no local content) and oh you can have a friend come over and queue (queue get it? see how smart they are?) their content that they have from the play store.
So it's pluses are neat queuing functionality and additional audio ports
it's cons are: no local content. can't run games, apps to your tv. and it's 300 bucks.
Scratch that. I don't kind of want it to fail, I hope it bombs. Reason being if it's a success less and less tablets will have hdmi in the future.
Again the nexus 7 is an amazing tablet, I just wish I had the version that wasn't downgraded for the validity of this device.
