3. Facebook (online social network, free) Facebook is a very popular way to stay in touch your friends' status, photos, plans, events, and more. But it lands at number 3 on our list because the application development platform it created last year is beginning to spawn some truly useful third-party-developed tools. Site

4. Microsoft Windows XP (operating system, not sold separately) It has been discontinued except as an option for certain low-end PCs, but XP is leaner, meaner, and less bloated than Vista.

Lenovo ThinkPad X300 (ultraportable laptop, $2500) As everyone swooned over Apple's hot Air, Lenovo snuck in the back door with a business-centric notebook that answers most of the Air's shortcomings.
