I like the gameboy advance. It's my favourite handheld (first time we could play doom on the go for one, plus it had a some good 16 bit conversions (Wings, IK+, Defender of the crown and Leonard made the excellent 'STsound' demo on it)) and I saw a video by retro games corp reviewing this little device and I must say was interested.
So I bought one (£33 from the powkiddy store) and I must say I'm impressed with it - though my only previous experience with a similar device is the deliciously ugly looking Chi Gameforce (a work of love, but ultimately not made that well) though I do like it).
This device feels well made with nice buttons that click when they should (not the d-pad) and it has no wi-fi, bluetooth or video-out (all a bonus as far as I'm concerned).
All in all a nice little machine that covers up to PSX and for the price I reckon it's worth picking one up if you like to play gba games (the screen aspect ratio is the same so there's no).
tl;dr:
The Powkiddy V10 is a cheap alternative to getting a gba in order to play it's games, plus it can manage other systems
