I don't have a lot of music and wont more than likely download a ton so I don't feel like I need a lot of storage room for it. So, I'm leaning toward the cheaper 3g but don't want to regret my choice.
Never mind -- I didn't realize the 3G was only 8GB. I don't have a 3G, but I would never buy an older generation of a product once there's a newer one out. You're just setting yourself up for problems when Apple decides to discontinue the model.
DH has the G and I have the S. I like it because I can put videos on it for DD. I mostly use it for news and books on CD, but it is nice to have for DD when we are stuck in the Dr. office or on long car rides.
Re: iPhone 3g vs 3gs
I'd say 3gs. but I think they're updating it yet again this soon (out this summer, right?) so you may want to wait.
