I'm interested in how fast other phones boot up. I know my old HTC Magic could take up to 90 seconds or more to get going. The Nexus One was faster, but still took over 30 seconds...often more.
How does your phone compare? Videos would be cool...especially if you have customised the animations (as a bonus). :-)
Here is a video I just made of the HTC Sensation booting up alongside another phone running a stopwatch app.
UPDATE: As suggested by NzBeagle, here is a video of a cold start after a battery pull. Quite a difference. see for yourself. Make sure you watched the top vid first. :-)
