Smart phones--they're a great concept. Combined are the powers of a cell phone and a PDA in one unit, letting you make calls, send e-mail, and work on documents without myriad gadgets; yet, these devices haven't exactly taken off. Why? Form factor may be one of the main reasons. To date, smart phones typically have been clunky and heavy, making them unattractive substitutes for your primary cell phone. However, things are looking up. Take these five smart phones, which are compact and pocketable yet don't sacrifice important features, such as wireless connectivity and PIM functionality. Read our reviews to see if one of these compact and light smart phones is right for you.

	3.	Nokia N73   CNET Asia rating: 7 out of 10 The good:  The Nokia N73 boasts a 3.2-megapixel camera with video-recording capabilities, an integrated music player, a vibrant screen, Bluetooth, and a speakerphone. The phone also had extra-long talktime, battery life, and decent call quality. The bad:  The Nokia N73's keypad is a bit cramped. Also, it lacks Wi-Fi and runs slowly when switching between apps or performing multimedia functions. The bottom line: The Nokia N73 offers a high-quality camera phone plus some nice extras in a stylish package, but its sluggish performance keeps us from giving it higher praises.

This Razr-like clamshell phone has been creating quite a buzz due to its tech-friendly Star Trek name and thin form factor, but its specs leave us wondering whether it deserves such a stellar title.
