I've been holding out for the myTouch 3g in hopes that it would support UMA and also possibly have an upgraded camera. Now that it's been announced and it seems like neither of those are the case, I'm trying to decide whether or not I should just pick up a G1. It looks to me that the only differences between the phones (other than the obvious physical differences) is that the myTouch has a larger battery and has more RAM. Can anyone chime in on what real differences the extra RAM is going to have. Will it only mean I can install more apps, or will it also affect the speed of the phone in general?
