RickH – good point. I used to use my N82 as a wireless hotspot with my laptop. I can't do that with the iPhone.
Having said that – the things I used to do on the go with my laptop were just simple things like email/basic web stuff, so I now use the iPhone to do those things.
I actually got an ipod touch in Nov 07, so was able to see how the iphone would work. Using the ipod touch was a good intro to what the phone would be like.
