I still have my xperia pro (mk16a). the battery is in bad shape (like half its original capacity) and the camera button works when it feels like doing it. aside from that it still works very well, I could use it as a high quality audio player since the sound quality is still amazing.
I also have (or rather not, a friend has it right now) a nokia 6630 still in working condition (don't know about the battery though) and loaded with all sort of apps and games, I used to copy full movies and some episodes of anime too (with subtitles, I have perfect vision), maybe there are still some there. I should try to get a stereo headphone adapter and listen how well its sound capabilities were since I only had a mono headphone adapter back then when it was my current phone and used it only when my main audio player ran out of battery.
