I usually run Ubuntu on my notebook, and I'm pretty happy with it, execept for the boot time : my laptop is pretty old, and Ubuntu takes about 50 seconds to boot.
Of course, that's not bad compared to windows (about 2 minutes last time I checked), but I was wondering if there was a minimal Gnu/Linux distribution which would bring this boot-up time lower, while letting me use the latest version of Firefox and Thunderbird (these are basically the only two apps that I use) I searched a lot before asking this, but it seems that either distributions don't provide Thunderbird, or they only provide outdated builds.
I should mention that my notebook is a 64-bits one.
Hope you have ideas!
