After my Thinkpad T30 got increasingly flaky (the memory slot failure issue hit me, then a MB flex issue (picking up the laptop on one specific corner causes the unit to freeze) as well as a cracked screw requiring a full disassembly to retrieve the loose metal), I did some extensive research online for a solid laptop which is not the newest model (so that bug reports can filter in).

I also ended up with a Dell Latitude D630. It's built like a tank, much more solid than my T30, easier to disassemble as well. I could not find any widely reported problems with this laptop. Note that because this is a business laptop, it only has a mono speaker buried under the keyboard, it's my only complaint.
