I'm reading bad things about Focusrite's drivers. But it's the 'net, so who knows?
Yeah, it's the net, but have you seen this site?
DAW Bench : DAW Performance Benchmarking
This guy, Vin Curigliano, has done some serious testing of interface latency over the last few years. Not a huge deal perhaps if latency isn't a huge issue for what you're doing, but if you were into VSTi's in a big way and overdubbing a lot, you might find yourself looking for something other than Focusrite, since they don't fare so well compared to others. (As a result of poring over Curigliano's comparisons and doing some clicking around on the net, I've decided that my next interface will most likely be something from RME. In the meantime, I'm happy with my Presonus unit (it has quite respectable latency performance, you'll notice), and from your own perspective, it's at a price point that you might be able to stretch to.
