I love mine. I had the regular 4, then about 3 weeks ago it ended up in the toilet , so I had to replace it. I was a little over a year into my contract so I was eligible for "upgrade" and ended up replacing it with the new 4s. I LOVE that. The dictation function for messages, email, etc., is extremely handy. And it is noticeably quicker both in processing and in web access (AT&T). Siri and I are just getting acquainted, so other than the dictation stuff, I have not talked to her much. I have a 16 an it is fine. If it starts to get full, I move photos and video (video is what eats it up) to my PC.

The camera is also great.

I have had a smart phone/email phone for 13 - 14 years, since the beginning. I originally had a series of Treos. For a time, I had a cell phone separate/in addition to the phone that did email. I think that was when smart phones weren't so smart and you couldn't email and talk at same time, etc.

It took me a long time to finally convert to iPhone, and in so doing, I betrayed my DH who has an ongoing Mac/PC battle with his dad (I am still otherwise PC - well, aside from the iPad.) But it was worth it.
