When shopping for a ThinkPad, IBM's web site can be a bit unwieldy, especially if you want to compare two models of the same series. For example, IBM makes almost 40 versions of the X40, and many are different in very subtle ways.
Luckily, there is a better way to shop. Head to IBM's 'notebooks literature' page at ibm.com, and download the PDF file tabbook.pdf. It lists every current ThinkPad model side-by-side with detailed specs and even the release date. Perfect!
Thanks to Bill at http://www.thinkpads.com for posting a copy of tabbook.pdf on his site.
