Own an imac that i use skype on for friends overseas contact.Would like some kind of portability without getting a phone.Wondered if this might be a good option?
in any case, both support skype. the ipad does not support skype outgoing VIDEO calls, as there is no camera - however with todays impeding updates this is likely to not be true (the ipad is rumored to have a front facing camera).
other then that, you can make voice calls just fine
The 4th generation iPod touch DOES have front and rear cameras, and an integrated mic. And Skype knows how to use both of them. So for the purposes of Skypeing over WiFi, the iPod touch 4G is just about on par with the iPhone.
If you're using an iPod touch 3rd generation, then there are no cameras, so a video feed, if present, is supported in the incoming direction only. And there is no integrated mic, so you need an external mic or headset to be able to produce an outgoing audio feed.
Skype doesn't officially support iPod touch 2nd generation or lower for video calls at all, either one-way or two-way.
