one of my k4's next-page buttons keeps double-clicking, so it skips two pages. it was occasional but it's getting much more often now, so i'm going to see if amazon will repair/replace it.
before i send it back i'd backup & clean up /mnt/us, to hide obvious hackery, but they're not likely to go rootling around the root filing system, right? any need to worry about reversing all the little changes?
it seems these days it's more likely to have a gadget replaced than repaired, so i'm also vaguely curious to see whether they'll send me ye olde grey model, or the new-fangled black one
