I've been looking at the Chinese Android/Linux emulation handheld scene for a few years now and while I think these things are really neat I've never bought one. They've always either been too expensive or too compromised/crappy with no middle ground.

The RG35XX H from earlier this year was pretty close- it had a horizontal form factor, Bluetooth, Wifi, a full set of buttons and analog sticks, decent build quality and performance that could easily handle everything up to PS1 (and could stretch just a little bit beyond that), and could be bought for less than 70 dollars. I hated that it had those in-line shoulder buttons a lot of these Chinese manufacturers love and I wished the screen had been just a bit bigger.

(To be fair, I wouldn't mind a device that could readily play DC, N64, PSP and even the Saturn, but that sort of performance seems to cost at least 130-150 dollars and would most likely end up costing about 200€ in Europe)

This new RG40XX H looks to be the exact same thing as the 35XX H but with a 4-inch screen and stacked shoulder buttons. If it's not horribly more expensive than the previous model I might finally end up getting one
