in regards to voice quality being bad is that on a 2g or 3g iphone?
I've got a 2g iphone. recent previous phones have been samsung blackjack (i320n), o2 xphone 2, o2 xda 2, palm treo, and before that had nokia 8000 series and carried around a pda too.
i dont understand how people can go over their download caps - unless they are watching youtube all day without being in a wifi zone. as there is an accurate counter that tells you how much you've downloaded, and most people would roughly know how large file wise each site they are visiting is? But as mine is a 2g one the net is quite slow when not within wifi, but i still couldn't see myself using the net that much more on it than i do. It is really handy having a device which you can access normal websites on without having to wait for it to turn on.
While there are many other phones out there that have more features than an iphone - the ability to mms for example. none of those phones are able to do the things an iphone does with the ease it can. Its exactly the same as how there are better mp3 players out there than an ipod - ipods win easily with userbility, even if there are massive crap points about it. I was watching someone on the train the other day with a samsung omnia i think they are called, and they were struggling to get the background image to apply with the orientation they wanted. Granted this is not something you can do on the iphone without buying additional software - it looks crap when you change the background anyway.
Zooming in and out on an iphone is dam easy, where other devices you often have to press a button to zoom in, with no option to zoom out, so is similiar to a dvd player when u start fastfowarding to fast - if that makes any sense. the keyboard is good, particually once you get used to the fact you're not ment to touch with the tips of your fingers. My gf dislikes it coz of her fingernails and the screen works off conductance - making her nails get in the way of viewing the screen lol. My bro is looking to get a touch diamond and i showed him web browsing on the iphone and how well you can control what you are clicking on, and i highly doubt anything else gets close - specially without using a stylus.
drop tests are on youtube. with any of the touch screen devices i'd recommend the cases made by www.zagg.com. after over a years use mine is starting to come off at the edges, but there is not one scratch visable on the entire phone.
Thats the main things i can think of - go into a store and have a play with one yourself. just dont NOT get an iphone just because its an apple product and associated with being a sheep - there are good reasons for y it is so popular. I did that with mp3 players and eventually bought an ipod lol, they are just so much easier to use for the effort on a day to day basis.
