Do you and I define "boot" differently? I define "boot" as going from a cold, power-off state to at the first user interactive environment (either a desktop screen or a log-in screen).
I'm not even sure my machines are fully done POSTing until about 5-6 seconds in (from a cold state). It takes about 25-30 seconds from power-off to get a desktop in Xubuntu for me. A fresh install of XP beats it by a few seconds (on the same hardware).
On a Compaq laptop I have which dual-boots Xubuntu and Windows 7, Xubuntu beats 7 to a desktop screen by a good number of seconds. Still, it's at least 20-30 seconds before Xubuntu is ready to go, and probably 45 before 7 is ready to go.
If you get a Xubuntu desktop in 8 seconds from a power-off state, I'd like to see a YouTube video of that.
the OS is only responsible for a certain amount of the total boot time. Comparing the times of "pushing the button" to desktop isn't the proper way to measure boot time for comparison to other devices. After hardware posting is complete and the BIOS starts reading from the MBR, that is when boot times start to be measured for comparison purposes. Most then proceed to stop when you hit a login or desktop.
If someone has a raid setup, for example, there is a good 5+ sec or more of added boot time that has nothing to do with the OS due to the added enabling of the raid controller which has its own startup routine. Every motherboard, bios, and setup has different amount of time required for hardware recognition and BIOS loading. This doesn't even take into account the different speeds of hard drives themselves which STILL affects the OS boot time.
