Hey guys, I am a physical therapy student who is really interested in either getting an Ipad or an ipod touch. If i were to get the ipad, it will be during the next update. But what i wanted to know was what you guys think the difference in functionality is for both products and which would be most useful. I already have a macbook, which i do my work on, but i wanted to use my potential product for more recreational purposes while occasionally doing some work. what do you guys think is more useful?
