The thing is though, BeOS in 1999-2000 was booting in 5-10 seconds on (in my case) a 300MHz Pentium II with 64MB of RAM and a PATA/IDE spinning disk. Even a stripped down installation of Windows 98 took several times longer on the same machine. I lived in BeOS for over a year and a half on that machine, only booting Windows for a few games. It was pure heaven.
