I have always liked IBM ThinkPad laptops. They are well made, reliable and outfitted with the latest technologies. Their biggest problem, however, is the price... Talk about sticker shock! With an entry price starting at a whopping US$2000, and then up, depending on the model, buying one will can you suddenly poor.
Still IBM laptops are good. So let's pretend you just won the lottery. The T40 is a 4.9 lb, one-inch thick computer. My test unit had a 1.6 GHz Pentium M Mobile processor though other models in the line are available with 1.5 or 1.3 GHz processors. It ships with either 256 or 512 MB of memory with space for up to 2 GB. Engineered into the T40 is a beautiful 14.1-inch screen powered by an ATI Radeon graphics chip. It's very nice when it works, although my test unit's ATI video card driver (the software that makes it work) was very buggy causing frequent, ugly crashes even on the stable Windows XP operating system.
Add to that a DVD/CDRW drive and you've got a nice multimedia computer, though the speakers on the system are a little anemic.
The T40 has lots of other great features, perhaps too many to talk about here, but I must mention the battery life. Wow! The lithium ion power cell provides 6.75 hours of usage between charges. Now that's mobile computing. Of course cheaper models in the T40 category offer less spectacular battery power- about 3.5 hours (still impressive compared to the competition).
The system comes with built-in wireless networking. The Wi-Fi antenna is integrated into the screen casing and the machine can work with either an 802.11a or 802.11b--the formers is a new faster wireless network technology, the latter your garden variety wireless technology.
Would I buy one of these? To quote from a Bare Naked Ladies song: "If I had a million dollars."
