On Psion Palmtop devices, innumerable Palm devices, then later on HP (and later Compaq) iPaq Windows CE handheld devices; Sony, Bookeen, iRex, Kindle, BeBook, Pocketbook eInk devices, and Apple iPhone and iPad. The only problem I've ever had was a faulty display controller on a Sony PRS-600, which was repaired under warranty.
