I just bought a second hand laptop with an ivy bridge i7 quad core, 16 gigs of RAM, backlit keyboard with firewire, usb3, eSATA, etc for 350 bucks and win 10. Still running my legacy M Audio project mix with win7 drivers and korg triton usb midi with no problems.
Fully upgradeable, easy access panels for maintenance, matte display.
Apple needs to start caring again because power users are fully aware of the potentially sweeter (and far cheaper) alternatives.
CoreAudio really isn't worth THAT much.
