Recently I got a new IBM/Lenovo T42 ThinkPad to replace my aged Toshiba Tecra 530CDT that I bought at a "discontinued" discount seven (!) years ago.
I was still using the Toshiba occasionally on the road, but with a Pentium 166, 64MB of RAM, and a 2GB HD, it was pretty long in the tooth.
I got a nice package deal on the T42, with two batteries, a docking station, a snazzy case, two power adapters, a security cable, Windows XP Professional, and Microsoft Office Professional 2003.
So far I really like the new machine. I got the 1400 X 1050 screen and boosted the RAM to a gigabyte. While I haven't done detailed tests, it appears the Pentium M 1.8 GHz will last in the neighborhood of four hours on one battery.
It's also my first laptop with wireless connectivity, and I immediately added a wireless access point to our LAN. It works great, but the new mobility taking some getting used to.
