I'm not gonna get into the 5" vs 7" debate. I use the system for android as well as retro gaming and some games just don't look right on less than 7" in my opinion. I would be perfectly happy with 5" though if thats all there was. It's the clamshell design of the xd i don't care for. The q9 with the psv controls is about as perfect as any game tablet i have ever owned. PLFI, the q9psv is literally identical two the old q9 with the exception of different analogs.
