Gosh, stop this either one or the other nonsense.

Boot times are important for only to a certain extent, then its only nice to have, but not essential. Personally my systems (Ubuntu and Debian etc) will boot between 15-30 secs and I'm happy with that - it no longer "frustrating" me. Sure a 5 sec boot is great, but that'll only be a bonus.

Like others, I care more whether it is slow during use. How long an app take to open up, whether switching apps is jerky, do I get an quick response from pressing a button etc.
