so all of a sudden i want an ipad..i told my gf about this and she responded by saying that i shouldnt get one because i already have the iphone4 and a mbp..Now, im a apple fanboy so adding an ipad to my collection would be nice..but i dont see the use of it if i already have the iphone and mbp.but i really want one..do any of you have all three? and what do you use them for?ANd is it worth it?
