[lug] What interesting things can you do with 4GB SD wafer?

[siegfried]

I noticed that http://www.tigerdirect.com/ still has 4GB SD wafers on sale
for $40. With an $10 adapter from Office Max, you can use it like a flash
stick (at least that is what I did with my 0.5GB wafer -- seems to work
great).

I ordered mine Sunday. I hope they honor the rebate. I wonder if the
entirety many of the popular distros can be installed in 4GB and then boot
from the wafer. Has anyone done this?
