What sort of 64bit software are you hoping for? There really isn't much out there in the way of 64bit at this point. Linux, unix, and solaris probably have the most 64bit software avaliable right now but it is more server related. Just hold out for Windows 64bit edition, then more 64bit software will start poping up.
