flawless, well almost.. I have some dust behind my protector however with knocking at the screen for some while I got rid of it and it's in the left corner of the screen now, behind the black boarder of the hard protector
The Hardware itself is GREAT. I was really surprised about the quality this product is manufactured with. I also can't share all the complaints about the D-Stick, ok it's slippery, but that's the only fault I see(besides some bad firmware checks on the microswitches that make it less accurate than it is in reality).
The Screen has NO dead or stuck pixel after all, it's perfectly backlit without any too bright or too dark spots(*thinks of the DS where the screen isn't fully lit in the same strenght). The native Resolution looks very crisp, however I can only tell by the firmware menu since my SD Card will arrive sometime next week...
I give that Handheld
For Hardware: 11/10 -perfect and even better!
For Firmware: 4/10 -bad battery management, scanlines on the screen, bad SD Drivers without full compatibility to all types of SD Cards, no 2GB SD supported, USB mode to win/linux is buggy(due to the SD drivers I guess), bad stick direction recognization, Movie Player doesn't play all formats it should and can crash(SD drivers again),...
Ok that's it. If GPH can manage to fix the firmware problems, I would give the system a 10/10 in there too.
