Most Thinkpads will work just fine out of the box. The hardware is great (I specifically like the keyboard and the little red point mouse).

The T series (and W series) are the work horses here with various screen sizes, disk options and RAM.

I personally use the X1 Carbon 3rd gen (X series) as it is comparable in specification to a Macbook Pro 13" (I have the one with the 16GB of RAM). It's a little costly but its worth while and will probably serve me for the next 2+ years.
