BlackBerry Curve 3G 9300 (AT&T)

Pros: Security, responsive trackpad, excellent keyboard, wonderful call quality, excellent battery life.

Cons: Web browser, camera quality, UI is dull, device freezes, heaven help you if you do not have a memory card.

Summary: Let's face it- if you ever have had a Blackberry, you know what RIM brings to the table, and you know where it is lacking. Any Curve is a lower tier smartphone, and the 3G doesn't erase this fact. It is a wonderfully dependable device, will hold up to constant usage with no wear to the trim or keyboard keys. In this day and age of high end, demanding devices, the Curve still sells very well because you get a great keyboard (duh, it's a Blackberry), wonderful battery life, and a trackpad which reacts to tiny commands. This last is extremely important, as the screen is small, and a less responsive system would blow past the selection you need. As usual, email is fluid, and security is so far ahead of other devices, it is not even close. No virus worries, no spam.
However, the downside of RIM and the devices they put out is that they pale in comparison to other devices in so many areas these days: user interface is stale (opinion) and very unresponsive (simply fact). The device often freezes, usually when uploading something or when processing commands that take several steps. The 624 mhz processor just seem unable to work at high demands at times, slowing the Curve to a crawl. The web browser is just plain bad when compared to mid tier to entry level devices running Android. Application selections are moderate at best. Buy a memory card, for you will fill the Curve quickly. The camera, video recorder, and other multi media selections are very fair, near poor.
