Pianoteq doesn't have a ARM version and it ask pretty much CPU.The Intel NUC seems interesting... similar to a Mac Mini (?). Actually that's what I'm thinking of, an core duo core 2ghz Mac Mini. Afaik it is known to be a silent device and has firewire, that's a plus for me atm compared to the NUC. Maybe even nice to see what OSX offers me in terms of CPU usage, get a bit experience with OSX etc. Regards, Dirk
