My friend Razi has an iPhone and he loves it. I met up with him recently and got to try it out myself and see what he liked so much about it. We both like Macs, but I haven't been so impressed with the iPhone.
I did get to watch some YouTube videos on it which was cool, but as far as everything else is concerned, I still don't understand why some people like it so much.
I like the idea of surfing the web, but if my battery died because of it and I couldn't use my phone, I'd be pretty upset. Maybe if they make an iPhone device that has incredibly long lasting and inexpensive batteries I'd be into it.
I asked him about service, but alas he was with Cingular prior to them being bought by AT&T, so their isn't much of a difference, if any at all. I use Verizon Wireless and am wary to switch to any other carrier, let alone for an iPhone.
