Yeah I have a flash drive as well... a 512 MB flash drive, which I often use to take big projects to and from school. The problem is that in my school, many people don't use floppies properly (usually ruin the floppy drive), so if you wan't to use any portable device it should be a USB flash drive.

I also have a 512 MB iPod which I use for transfering files, since I don't use it a lot it's sort of used for storage now.

It's extremly handy to have a USB flash drive (or an extra iPod) around!
