The biggest speed-up to my cold-boot time was when I switched to SSD - time from grub to login screen is now just a few seconds. Interestingly, that changed my usage habits; I started shutting down my laptop more often and therefore had fewer problems with peripherals not initialising properly after waking from hibernate (eg sometimes my touchpad would move the mouse pointer rotated at 90 degrees), but mostly I started booting into my Windows partition more often instead of using Wine etc to try to run programs. A faster boot time made it more trivial to switch between boot options, which I see as a good thing.
