exactly. In the next few years wifi is going to be everywhere. you will be able to pick up free hits from any mid sized town. Sitting at my kitchen table in a suburban neighborhood I already get 12+ hits, many of which are unlocked. an iPod with wifi means everyone will have some sort of use for them.
honestly what teenager uses the home computer for anything but the internet and instant messenger? maybe games, but hardcore gamers aren't going to be running on a mac anyway. if the ipod had wifi parents wouldn't have to buy a computer for their kid, they could buy a 400 dollar iPod and their kid could do everything they wanted with it, and the parents could keep their computer.
10-15 year olds, iChat and their blog (myspace or xanga)
16-22 year olds, facebook, email, news, youtube
23-30 year olds, email, stocks
the list goes on. an iPod with wifi means a happier world.
You've got to be kidding? An iPod, or iPhone for that matter, isn't a suitable replacement for a computer.
Most portable devices are trying to replicate the feature set of a computer and put it in your pocket. If you're sitting at home, I don't see many people using the portable device over the computer while at home unless you need to use it somewhere other than where your computer is.
If mom and dad want the computer back, they're getting the kid a Dell or Wal-Mart special. Or better yet, nothing at all. The great thing about being parents is you can tell your kids "No! Not yours!" and that's that. Parents don't, and shouldn't, have to buy their kids something else so they can get the computer back.
