2. Apple iPhone (smart phone, $400 with two-year AT&T wireless contract)
Rarely have handsome industrial design and breakthrough technology (including the supercool multitouch interface and visual voice mail) mated so happily as in the iPhone — and the rest is history. Review | Check prices

3. Facebook (online social network, free)
Facebook is a very popular way to stay in touch with your friends’ status, photos, plans, events and more. But it lands at No. 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. Despite the outcry from users, however, at press time Microsoft still planned to retire the OS on June 30, 2008. Review | Check prices

5. Lenovo ThinkPad X300 (ultraportable laptop, $2,500)
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. It has processing power to burn, plenty of ports — and a paper-thin optical drive. Stick that in your manila envelope, Steve. Review | Check prices

8. Casio Exilim Pro EX-F1 (digital camera, $1,000)
The 6-megapixel EX-F1 captures video at up to 1200 frames per second at its lowest image-quality setting and shoots full-resolution (1920-by-1080-pixel) images at 60 fps. Video review

9. Harmonix Rock Band (game bundle, $170)
All you need is your PS3, Xbox 360 or Wii to get the band back together. Really, “Rock Band” is “Guitar Hero” times three: It puts you on tour as a guitarist, singer or drummer. Video review | Check prices

10. Wikipedia (open-source encyclopedia, free)
This online trove of information has more than 1.6 million volunteer-contributed articles on everything from Britney to biochemistry. It becomes more credible and reliable as more people check and edit the entries. Site
