I have an iPod touch 1G , and it is very versatile, you can download applications from the App store, which is very powerful in such that a lot of developers are making something for every persons wants/needs. now the call quality i here is improving with updates, and thats the downfall with the ipod touch/ iPhone, is their software isn't c done, so updates are applied, and they are , i feel, getting closer to finishing the iPhone OS.
As for the person saying the touch screen is really sensitive, well it kinda has to be for it to be a touch screen. most people are used to a stylus screen, which is pressure, not touch, sensitive.
There are many features of the iPhone, such as an accelerometer.
pretty much i think the iPod touch/ iPhone were the best thing that happened to the market, both Phone and mp3 players.
the only down side.. is the cost of the plan.
The average phone bill of an iPhone user is $95, almost twice the average of all other customers. If you’re an average iPhone user, you are spending $540 more per year, or $1,080 over the life of the two-year contract, for the privilege of buying an iPhone for only $199.
