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.
-no loading sd card
-never have to worry about apps taking too much memory and getting the "low memory" notification
-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?
