I've just installed the new PCLinuxOS MiniMe KDE 11.07 to
a 4 Gb SanDisk USB with very satisfactory results. This is
a minimal initial LiveUSB install that allows you to make
your own final product via synaptic.

The only problem I had was that MiniMe would not retain a
1366x resolution at first. The developer corrected that
in about two or three e-mail turns.

This might provide some here with a diversion while waiting
for whatever comes after Knoppix 6.4.4. I recommend it.

Among the enticements are squashfs, 2.6.38.8 'bfs' kernel, and
wireless that handles my Broadcom wifi (not many distros do).
