Abby, would you believe none for me in this day and age? My wife and two kids have one, but I really have no use for one myself the way things work out in our daily routine. Plus, they frustrate the life out of me because they're so small and I need to put glasses on to work the thing.
A Samsung SGH-X640. Meaning almost the most basic phone available. If somebody still sells them that is. But it works fine for me. Just being able to make calls and sending text messages is all I really need. Should it die I'll probably just buy something similar and nothing too fancy. I have better use for the money.
A Samsung Blackjack. It has been the best phone I have ever had, overall. I loved Nokias back in the day, and tried a couple of motorolas but they were pretty much crap. I've had it for over two years and the only problem has been that 1 battery died and the cover for the charging port is loose. I think I want an HTC TouchPro next, or a touchscreen Samsung.
I've got the red Blackberry curve as well. I have to say that it's the most *functional* phone I've ever owned. I like the QWERTY backlit keypad. The screen has a higher resolution than most Windows Mobile Smartphones. I keep my checkbook on it. It pulls email from all my accounts. It plays my MP3 music. It's even compatible with Pandora Radio. I got it for a whopping $99.
