As a sophomore in college who owns a Lenovo X61 (Tablet PC) and takes his organic chemistry and physics notes on it I HIGHLY recommend it. Using Microsoft one-note allows me to annotate PDF's Word documents, basically anything that can be printed can be virtually printed into one-note and annotated. Onenote also scans the printed document, indexes it, and allows you to search it for key points. The software and tablet function are extremely powerful tools, and also allow one to kill less trees if you are a staunch environmentalist.
On another note, the battery life is fantastic. I have gotten more than (barely) 5 hours of typing time, and 4 hours using wireless at the same time. I go on one charge all day with the extended battery. The laptop is extremely flexible in its abilities and is very capable of handling multimedia (No video editing though, obviously). It weighs just around 4 lbs, which is ridiculously light. Also, the laptop has a setting that can make the computer hibernate and allow you to switch batteries without losing your data if you switch them quickly enough. It is an amazing machine.
The drawbacks are price (~1200$ if you go refurbished like I did), screen size, and lack of attached CD drive. The screen is good but does leave some to be desired on sunny days. To be honest, the lack of onboard CD-RW drive is not a big deal to me. All of my music is digital, and when I want to import something I stick it on the base which has a drive.
