A short while ago I mentioned I'd switched my laptop to Debian Testing (from Ubuntu 10.10 "Maverick Meercat").
That's not quite true anymore. Having done a bit of research, it turns out that Debian Testing is probably not the right version of Debian to use, primarily due to the slight delay on getting security updates out to it (there's a week or so delay often, sometimes more). This seems to be "as designed", and the way the process works.
So, taking the bull by the horns, I wiped Testing and stuck Stable on my Thinkpad X60s. Everything seems to work still and I'm happily using it. Looking back on the history of Linux, Debian and laptops, this is definitely something worth celebrating. We've come a long way ....
