I just installed the RTM version on the MAC at work today, took 25 mins to install in parallels, just installing VWD & SQL 2008 at the minute. It's running nicely at the minute and recognises all my MAC components (had problems with sound and graphics on beta).
Pity leopard is being a c*nt and won't let me install snow leopard.
On a slight side topic has anyone on here had a chance to install the new Psystar Rebel EFI software? It allows you to install OSX on your PC at home for around £40 if you wanted to try it out as an alternative to Windows or just as a dual boot.
