FYI: Linux on a Vaio VGN-TZ21
Just thought I'd share my limited experience on this brand new, rather expensive mini laptop. I'm a SuSE fan, but couldn't get 10.0 to work at all, the display driver just wouldn't work on the Intel chipset.
Ubuntu 7.04 however worked straight away with no tweaks or adjustments whatsoever - and 7.04 isn't even the latest version. It is much faster than the non-working SuSE was and much much much faster than the Vista that came with it!!
So if you have this laptop, give Ubuntu a go....
