Didn't they say that new model will have better cpu inside?
I don't have any of this devices so i wanted to give it a try, but now i am not sure if i buy old model will i have some problems in a near future.
I know they said that they will support first model but who knows for how long, because they will probably want to stimulate sell of of newer model and not spent time on support time for the old one.
It has a faster processor yes. If you don't mind adding almost 50$ and wait little bit for the shipping then I guess it would be better to buy the new version instead. The old version shouldn't stop working at anytime but there will be definitely lack of features in long term.
That's what I am afraid of the most "Lack of features in long term", for device to become obsolite
