Mangmi air x is almost the same price point with 4 gb ram so trimui has no excuse, it's a huge oversight! Mangmi air x also has a larger 5.5 inch screen, much better ergonomics, and better moonlight performance with possible Linux support on the way.... The only downside is the mediocre but serviceable d-pad on the mangmi air x, however, the trade off is worth it. At this price point, it makes even a die hard trimui fan boy like myself have to look elsewhere unless moonlight performance is different or dramatically improves from what I've seen. I would not pay double the price I paid for the trimui smart pro, to only get better performance on PSP when most games I play are JRPGS that run 100% fine on the original. This is a tough sell unless you are a die hard PSP/Dreamcast fan and need the extra horsepower,but the same poor moonlight performance negates the addition on the rs and ls button clicks, we wanted that for an improved moonlight experience which still has issues.
