I actually regret getting the big wifi version. I should have gotten the 32 gb 3g one
It really depends on how many videos I have loaded at any given time.
On my 16G wifi - looks like I have used a little less than half! and I feel like I have a ton of stuff installed on it! Look out world!!
With as much as I use this thing i figured it was totally full....I honestly can't fill it!!
I've got other stuff for storage, I've only got what I need on it at any given time.
