Another laptop recommendation thread....

I have to buy a new laptop for my boss. It's a desktop replacement and some
of the requirements are, large screen, big HD, lots of memory and XP Pro.
In the past we have used Toshiba, Micron, Dell and they all had to be sent
back at some point for repair except Toshiba.
I am tempted this time to get a Thinkpad. What are you thoughts,

Thank you.
