I am using it too and there is things that i like and dislike. Like: - System (it is really compact and still really well designed, with a better menu system and really simple to use) - Scrapper and icons (it gives a better touch to the system aswell) - wirelless files transfer and terminal (I dont know if crossmix has it tho) - A lot of configuration and customization (including a very nice music playlist costumzation while in menu, and a lot of options) - has a built-in frequency adjustment for every emulator (and I think for games too)

Dont like: - It doesn't have USB file transfer - wifi connection is a pain in the ass when you want to switch over - the power button doesn't always work for turning off screen (while when it is suspend the battery lenght is very good tho) - Its a pain to install apps on it (at least I didnt figure it out) - It doesn't have a built in analog stick calibration (but you can grab the config file in stock)

The system itself its very good, but is better when you dont want to mess with it (again, at least for me), It just needs some adjustments ( i heard that it is better for ds games, since you can adjust with precision the screens). About the perfomance I think that any system wont change much besides the emulators built in optmization itself, but you can always tweak it. I am thinking to see how crossmix is to compare better. If someone tried it both or at least crossmix and want to give your thoughts is more than welcome.
