I believe I have the computer you recommended, a work T61, and a Macbook Pro. The keyboard on the MacBook Pro is much better, surprisingly. The idea to use a backlit keyboard is incredibly thoughtful. The screen is much, much better than the one on a T61. The operating system is much better and simpler, with not a single picture or theme of a blue sky that I know of. The T61 wins in... looking Windowish.

In this case, both Windows XP and Vista computers look as unrefined and ancient right now as old Apple computers with 5.25" drives do. When I think of Windows I think of those documentaries about the Silicon Valley from the late 90's.
