I bought a Dell Inspiron 8200 a while ago. The unit came with a 15" UXGA LCD, 2GHz P4M, 256MB RAM, Radeon Mobility 9000 64MB, 24x CD-RW/DVD, 40GB Hitachi 5400rpm 2Mb cache - integrated 3Com 100Mbit LANcard and 2 PCMCIA (spell-check!) slots.
I then added another 256MB RAM to boost the performance.
I have had the laptop for 4 months now. There has been no problems at all, which I didn't expect either. The performance and stability is top-notch. There has been zero crashes or hard-locks during the entire time. I play Warcraft III, C&C Generals and other current games on it without crappy performance, the games run smooth.
I use it mainly at university. I study to become an EE and mobility is a big help, when I go between the different laboratories out there. The only thing which bothers me about the laptop, is the placing of the RJ-45 port, which is beneath the palm rests on the left side of the laptop. They should have placed it at the back instead.
