Are you sure that "best" is a good idea? Maybe something that works would be ok? Did you try the iPad?
I am going to be traveling abroad for a month and I want to video skype with my wife. I normally take my laptop with me for this purpose, but I was wondering if I could find something much smaller to do this with since I will not need my laptop for anything else on this trip. I thought that a tablet would be the ticket, but after doing a little searching, to my utter amazement, skype is just now starting to support Android. Also, most tablets only have a front facing camera. Then I began to wonder if there was a smart phone that could be used for this. Since they have been around longer then the tablets, I thought that might have better skype support.
