Your questions answered in order,
1)Is it 64bit?
Yes BeOs is a 64 bit OS built from scratch on the BFS (Be File System) a journaling file system
it has system protected memory, preemptive multitasking qnd supports multi-processing and multi-threading.
2) Is it Pure GUI? I mean not like linux or windows 9x series, which is a fancy gui on top of a dos box.
Yes, it is a pure GUI OS really designed as a multimedia OS but uses a a Unix-like kernel
which is accessible from the command line running BASH.
3) Does it boot fast compare with other oses on your computer?
Nothing can touch it when booting or shutting down, I am in Be right now or I would time it, from after the time
when the PCs BIOS does it's thing like the POST, count the mem and find all the HW and starts to load the OS I would guess
Be would be up and usable in about 10 seconds, shutdown is the same way.
BeOs was and IMO still is the best OS out there, if you have the bandwith to check out this movie do so and I think you
will agree that neither Windows or Linux can do what Be is capable of and remember the HW that this is running on. Not
wanting to turn this into an OS bashfest because I run Linux and Windows OS'es, but check this out go to my post here
and check out the link to the movie.

As far as BlueOS goes it does sound promising but I think there is more possibilty and potential with OpeBeOS or OBOS, check out what this
is all about too.
