Does anyone have any thoughts on whether the 512mb of RAM included with the g2x is going to be enough to future-proof the phone going forward? I think the specs are pretty awesome on this thing otherwise, but 512mb of RAM concerns me, as the other new phones (evo 3d, galaxy s2, pyramid) all have similar specs but more RAM (either 1gb or 768mb). I don't want a device that is going to lag if I have a few things open, and I don't want a device that can't handle any one big process (like a game or anything really)...
