ichat is a computer device not a phone device
That's quite possibly the most ridiculous thing said here. People are using a wide variety of smart phones to Chat instead of text. I feel people have come to expect it from their phones actually. For apple to have internet capability, a makeshift querty keyboard, and OS X on the phone- where's the iChat? I agree, and furthermore, will not purchase one until it IS on there.
And don't tell him to calm down, he paid 600 bucks. He has the right as a consumer, and to belittle people for wanting features, well, you've officially entered the Gates (Bill) of PC Hell.
BTW, Why hasn't anyone pointed out the obvious theory that maybe AT&T begged Apple to not allow iChat so they can rack up text message fees. I mean, SMS looks like iChat, makes the sound like iChat, but be careful to not go over your limit! And, no buddy groups. I have several groups of aim'rs professional and friend and benefit greatly by accessing them when mobile.
EDIT - also, maybe AT&T has the fear that once iChat is available, why not iChat using voice? Then they're missing out on SMS and minutes. They'd have to prorate their data plans and send 1400 page bills detailing every kilobite (yes, yes, I know it stopped so don't reply to that. sheesh)
Viva iChat on iPhone!!!!
