Yeah I got:
a couple batteries because they seem to wear down,
and another touch screen and tools to install it but am still using the original (fairly scratched) one,
but my biggest problem is that some old voltage shorted a circuit and now a keyboard backlight stays on (even when the device is off), and the microusb port doesn't get enough power to run mass storage nor the flasher.

I don't use the device very heavily, mostly just as a filing system; and music player; and to read the internet.
