I guess the levels of handheld emulators would looks like this:
lvl1: really cheap and crappy handheld mp4(mp5) players
they work, but god-awfully.
sold about 30-60 bucks
lvl2: gaming gozillas, psp, ds, apple stuff
they either not portable, or not easy to use
dingoo a320, jxd3000, letcool, wiz, gp2x, caanoo, letcool
those are the ones you're looking for
cost anywhere between 70 to 140 bucks
pandora, mbook m1 etc.
those are too expensive, and not easy to get your hand on.
cost about 500 bucks
we can see there is a huge gap between lvl3 and lvl5, there suppose to have lvl4 stuffs.
lvl4 handheld suppose to be more powerful than lvl3 handhelds, and less expensive than those handheld pcs.
I guess a tablet with buttons fits in this category perfectly.
perhaps, this RG opens up a new door for games. This mighty category of tablet pc with buttons may crush every other handhelds, with their nice performance, good build quality, and a just-right price.
I guess, this is very likely to happen.
