You can use google voice and talkatone over wifi. You also get free texting with this. If data connections become possible for the touch you can use that as well. This is how I turned my iPad into a "phone". It actually works better than my current dumb phone. seems to me we are starting to blur the definition of a phone. I personally would love for the touch to come with a data plan, since I would then not need an iPhone. I could get a 3G capable touch, use google voice, keep my dumb phone and it's pre-paid calling plan as a backup, and be very happy.
