Yes, thanks.

I know that I don't have to use MyDocs, and I have a /Documents on... somewhere. Though moving /MyDocs was no more work than moving /MyDocs/.documents/Maps, which was hiding 81MB here. And it's easier/quicker to change directory in some programs than others.

After Symlinking, I had to charge two nights in a row. That seems slightly more but it's hard to say since I probably used it more actively.

du | sort -n | grep -v media reports that I have way too many MB in /usr, quite a bit more than you'd expect in a 256MB partition. Most in /usr/lib, /usr/share and /usr/bin. I assume moving /usr/lib would mean a general slowdown. But no more than cloning the system to the SDHC, I would also assume.
