I currently have 32GB and it's pretty full. I'd really like 100GB or even slightly more so that I can fit all of my music collection on it; I really hate having to cherrypick down the selection.

I only have an 8GB card in my 'droid but I've never actually run out. If I felt the need for more space, then it's really not expensive at about 50p / GB right now.

Just checked and there's only 268MB free. However, that's because there's a few videos on there which I've watched already. If I want something new to watch, I'll simply delete the one's I've seen.

My Android phone has about 1GB built in and a 4GB SD card. I have about 2.2GB on the SD card, but the phone is about full (15MB left) which is a pain. Apps have to be installed on the phone before they're moved to teh SD card (assuming they can be, many can't).

My next phone will have much more internal storgage!
