The features I'd like to see on a g5a plus model would be increased ram (2gb), vibrator motors for n64 rumble pack emulation/haptic feedback, and a better d-pad. I'd keep everything else the same. Screen resolution is kind of a double edged sword on these devices. IPS would be nice, but it would be more taxing on the GPU. I suppose it is inevitable that they would upgrade the screen on a plus model, and I would enjoy the better viewing angle, but I don't want a huge performance hit! The only other upgrade I'd do to the g5a is to try to include a wrist-strap anchor somewhere on the side of the unit so you could attach a wrist strap. I actually attached a wrist strap on my g5a. At some point I'll write up a short tutorial in case anyone is interested.
