I think I'm the earliest one here so far. I bought my i6000d right when they released the graphics card for it if I'm not mistaken somewhere around Feb 05. A couple of problems here and there but nothing too serious. I'm very happy with it.
edit: only complaint is the fading palm rests but that's practically a given. There's nothing i can really do about it except change the shell.
had mine for about a year, before that my brother owned it, and when i got my m170 i traded him my 9300 for it. its a nice little machine, and there have been a few problems (dvd drive, lcd, battery and hard drive so far) but nothing huge. it get hotter than hell but i leave it on 24/7 so i suppose it is normal.
