Like SheFly I've never upgraded from a dumb phone, but I have used a smart phone enough to know a little of what I'm missing. I have a basic, compact waterproof and shockproof phone, without a keyboard. I don't miss the keyboard, I message faster than I think anyway ;-). I'd prefer having a better camera, and sometimes I miss a better and larger screen. However, I really like having a small and bombproof phone without a large glass screen to break.

I haven't bought a smart phone because I know I'm too addicted to the net as it is, and would find it hard to not check email and facebook and TE all the time. I enjoy the downtime. But on longer vacations it's very handy having my dh's smart phone around, to check the news, the weather, email every now and then. But texting on it drives me up the wall.

I know I'm missing it out on various apps, though, so I may switch at some point anyway.

On another note - any tips on how to stay OFF the net... ;-)
