Yes, you can install it on a drive to use it natively. Going with SFS, it's a bit tricky to do the install, but there are instructions on how to do it (or jump over to #aros on irc.freenode.org for semi real time help if a Dev is at the keyboard). There is UAE for Amiga apps. There is also
AROS-Max distro which has both native, hosted, and emulated ISOs.
Current active projects:
ATI driver (nearing test release)
USB
x86-64 port (major rewrite of kernel to allow modular support)
Though we do try to post to AO, alot of more info is posted over on
AROS-exec.org.
