Have an iPhone, worth it. Ignore the nay sayers. The Edge network is fast enough while on the road. I surf while waiting in line, check my web cameras while driving on the turnpike, have all my contacts loaded, check stock quotes.
If you're hung up over 3G you could wait to see if they come out with the new version. They're supposed to announce what will happen in the UK on Tuesday. It's going to be a huge day because Apple is having the UK press conference, and Ben Bernanke will cut interest rates. The question is whether he'll cut rates by 25 basis points or 50. There are rumors Apple will talk about a 3G phone for the UK, but right now that's just rumors.
The iPhone is great because it has everything you need in one device. Yes, the clones might be better in other areas, but no one talks about the negatives of them. So you hear a bunch of nay sayer chatter. I like the iPhone and I'm ok with paying $600 bucks for it. I will get $100 back which I'll use for a new iMac when Leopard comes out. And everyone can get over the geek stereotype of Apple products. People are buying them because they work.
