I for one would like to see numbers for

- boot time
   - time to gdm-autologged-in 
firefox-autostartonsession-viewing-local-htmlpage

- number of laptop drive spin-ups per hour
   - i.e. boot like above, then leave system idle for a few hours
   - also try leaving other common apps open when idle, i.e. thunderbird,...

- time for kernel compile
   - i.e. same as original test, but with what I commented, i.e. reboot 
before both tests to ensure accuracy

- time for find / -exec grep "somestring" '{}' ';'

- time for tar copy of rootfs to a different filesystem

- time for reconstruction of f7/f8 media (livecd and traditional) via 
livecd-tools and pungi (or revisor)

- anything anybody else adds to this list...

- oh, and did I forget to re-emphasize the laptop spin-up test...
