Takes me less than a minute to boot. from the selection screen to desktop. But i also have SP1 slipstreamed into my install and it is only about 3 hours old.
About 40 seconds from password input to desktop with all the icons in the taskbar loaded. However, an additional 60-90 seconds before I'd even consider selecting anything. If I do, it's slow as balls. If I wait the 60-90 seconds, it seems to be more efficient then.
About 30-35 seconds as well, but without opening my 2 external hard drives (750GB total capacity), if I have them opened it takes about 2-3 minutes to boot up.
