i believe both have their ups and downs. heres what i think are the good parts of them. i was going to put cons down but now that i think about it, the cons of each, are not having the pros of the other. Internal -Quicker -no loading sd card -never have to worry about apps taking too much memory and getting the "low memory" notification SD -easier to move files/share files -upgradable, not built into phone Personally, i like having an sd card alot more. What do you guys prefer/think about this? Anything to add on?
