My first impressions are very positive.
It feels solid.
WIFI is very good. Better than any other previous console of the kind for me.
Controls mechanically look very good too. I'm no dpad fetichist
They will need some fixes in the kernel for enhanced performance and ranges.
About the "feel cheap" comments, in my opinion mainly come from the color and the "GamePad" writing under the screen. This is a small style detail.
Shape wise the device is very nice. I think it would be rather easy to respray the case. I still think that this device on a dark red, olive drab or tan would look awesome.
