Query: Very poor quality hardware

I've owned a Treo 90 for just over six months now, and I've had to return it four times. Once for a broken keyboard, and the last three times because the backlight failed on the color screen.I'm disappointed because I liked the small size, the handy little keyboard, and the flip-cover that protects the keyboard and screen. Unfortunately all that nice design is fouled up by the really lousy hardware quality.My previous handheld, an old Palm III, lasted years and years. In fact when I upgraded to the Treo the old Palm was still working and I foolishly gave it away to a friend. Shouldn't have done that--now I'm gonna have to buy a replacement for the Treo 90.
