Thanks to everyone who participated in the great Mac or PC for Music? debate a couple of weeks back. The result was 22 votes for Mac, and 13 votes for PC, so I ended up buying a bottom-of-the-range 2.4ghz iMac, which works nicely (after a bit of messing about with DNS addresses). Assuming that cheap Logic Studio from Amazon isn't an ebay-style con, that should be arriving soon, together with a pile of non-Apple Ram. I'll probably get a used Motu 828 mk 2 firewire, unless that's a terrible idea (I need a few inputs, so won't be buying an Apogee Duet, before you mention it).
