Well. I think i can say something about it 'cause i also have one.
1. The advantages and disadvantages i will pass because time will tell you the truth and i don't want to be deemed as a advertiser.
2. You can play many emulator games on JXD s7800b, such as GB, GBC, GBA, NDS, N64, PSP, PS1,FC, NEO-GEO, MEGA, DC etc. It's wonderful. And another good news for you is that you can download all these games freely on Happy Chick(http://www.xiaoji001.com/download/xiaoji_jxd.apk
in).
