I had two Portege 3020CT's that died on me recently. They were some of the best laptops I ever saw. They were ancient but lasted forever and took so many drops, hits and other physical abuse with absolutely NO PROBLEMS.
Then I bought a successor.. the Portege 2000 a little while back. First week, I snapped a piece off the case where the lock goes in. Other than that, it has handled some of my abuse. But overall, I think it is really slow... so Toshiba dropped the ball there.
In terms of the best laptops, I guess the IBM Thinkpads would be at the top. If you don't mind Macs, their offerings are pretty impressive. At the value end, I think the eMachines are fantastic for the price. Some of the Dells are okay as well.
