On my machine (2.8Ghz P4 with 1.5GB RAM (dual boot XP and Vista)) startup
time for XP and Vista are exactly the same 110 seconds. That figure is from
a cold start. However, as Jon mentioned 'the startup doesn't end with the
loading of the desktop' There are lots of other processes that are loading
in the background which add significantly to the time it takes Visat (or XP)
to boot. Strangely, as an example, I quote 110 seconds from a cold start to
everything loading (i can use applications well before the 110 seconds but
they will load somewhat slower). I recently installed the beta copy of
VMWare's Virtual Machine. This just shows what happens when applications
have to load processes. From cold to a full desktop without VMWare is 110
seconds. With VMWare installed startup time is increased to nearer (although
i haven't timed this exactly) to 170 seconds. At 170 seconds i've got time
to have a knap

So, basically, the more applications and/or processes that
have to be run will drastically affect the time it takes Vista (or XP) to
launch to a fully functional desktop.
