Scott and Jim Rosebury are the two DAW builders I was referring to. I didn't know there were other commercial DAW builders on the forum. One of their suggestions is to hold off on Win 8 for a while to see how it pans out or if there are stability problems.
My Roland Octa-Capture has Win 8 drivers.
I had a Firewire interface device, a Focusrite Saffire Pro 40, but as it was Firewire I couldn't use it with my laptop (for on-site) recordings. When it died I replaced it with a USB device, which works with any PC I have and I have lower latency with my USB interface units than I did with Firewire.
