+1 for Focusrite, great drivers, rock solid and supurb products.
Their LS 56 is great, and no, F/W is not going anywhere soon. And even if it did, with an adapter Thunderbolt/Firewire you're up and running for more than the lifespan of consumer products as Focusrite products will work with one.
My 2 eurocents !
Cheers,
Jerry
