The old one was an IBM Thinkpad t40p

1.6GHz Centrino, 40GB HD, 1GB RAM, bluetooth, wireless, CD-RW/DVD combo drive
The new one is a Dell Latitude D610

1.86GHz Centrino, 60GB HD, 1.5GB RAM, bluetooth, wireless, CD-RW/DVD Combo drive
They both weigh about the same. The IBM was a little thinner, but the Dell doesn't have the monster battery hanging off the back, so it will fit nicer in my bag.
Not that I had much of a choice here (we were given the choice between 2 Dells, the 601 and 810... and the 810 is friggin' heavy!).
Now... to transfer a few gig of crap from one to the other before I apply the cleansing flame (mental note to self: back up your friggin' fonts this time, dumb ass!).
