I have a HP 4150, used it for emulators, music, web browsing, watching films, Quake and note taking. For the last year and a half it has lain in my drawer with a shattered screen after I played pool with it in my pocket. It was in the protective case and everything. I could easily fix it, but in all honesty I can't be bothered. It's worth about five pence now and every other device I have does what it did better.
After seeing the heavy use mine got, my brother ( 7 years old at the time ) asked for one for his birthday. I asked him what he intended to use it for. He replied "Agent things" and so it lies in the drawer a year on unused.
