Nokia is not bad. I bought iPhone this week, and found that Nokia actually is very user friendly.
From iPhone, you can not attach documents in to the emails. You first need for example have the picture, and send that one-by-one. You can use Nokia email client more like to normal computer.
iPhone does not synchronize over bluetooth, for example pictures and videos has to be transferred to computer by cable.
Nokia e72 has fast 3G with 10Mb download speed. This is far better than any of the competitors. In case the network connection is sufficient, e72 has the fastest 3G on the planet. Period.
iPhone does not support flash, except on the youtube. So you can not see other videos on iPhone, but you can do with Nokia.
There are many things that I THOUGHT iPhone has, but in reality it doesn't. I thought iPhone has superior email and internet features, but in techical terms Nokia has more features, better performance and is more usable. Nokia can even syncronize iTunes playlist easily; a feature that doesn´t come to your mind before you try and learn. Naturally iPhone does that as well, but in HK there are limitations in the iTunes store; something that doesn't come to your mind before you try.
What comes to phone selection; go out and try all the features that you might want to use in the future.
