After the watching the keynote earlier today i'm wondering whether I want to purchase an iPod Touch or an iPhone. I wouldn've want to activate the iPhone to AT&T or any phone company, but with the similar prices, am debating both. On eBay a 1st Gen Touch is about $130. A 2nd Gen for about $160. The iPhone 3G today is now at $99. The 2nd Gen Touch appeals to me since it has microphone capabilities and therefore would be able to use Skype and make calls when im in a Wifi network. But I'm wondering if the iPhone is completely useless since it won't be under a phone carrier network. Would I still be able to use Wifi and enjoy the iPhone 3G in the same manner as an iPod Touch with the added bonus of the built in camera and the microphone being built into the phone as opposed to the microphone earbuds for the 2nd Gen Touch? I'm still debating this but insight on the matter is really appreciated as i'm getting ready to make a purchase super soon.
