When ever I record on my iPhone I have to delete the videos in a few days because most of my space be gone. 16g is cool at times!!
which apps? last I checked, probably most are less than 20 mb, unless you're thinking of games.
I've managed with 16gb okay... 6gb of pics/video (I have a daughter), and then various utility apps. I recently downloaded star walk, and that's 50mb, despite loads of info. (I also don't bother to put music on my phone). and with the higher resolution camera coming soon, that will eat even more storage.
what concerns me more than flash storage amount is the amount of data many of these apps are downloading/uploading. play scramble with friends, and you can kiss your data plan goodbye. soon, data needs to become cheaper to account for the 'connectedness' many of the hyper-visual apps require (read, Facebook).
I'll echo a sentiment often found in the mba forum: if 16(or 32) isn't enough, then surely you're going to need more than double that amount.
