You know what you just made me think of? I wonder if Apple couldn't change the model we're used to with wireless phones! They did it with the iTMS, didn't they?
I wish they would do something like that - a WIFI model. Something you could use like VOIP for calls (Vonage?), and hotspots for surfing. I also think that the number of places with free WIFI access is growing. My office phone is a Vonage phone, and it works great. In fact, I'm on the $14 a month plan, and I don't even come close to going over. One thing I do like, is that voicemail is sent to my .mac account.
