Where are you located in the world? US, Oz, UK?
By 'interface' I think what you're meaning is a mixer with a USB out, right? If that's the case, you're probably right about it being easier, but I don't know about cheaper and more than likely not 'better' unless you spend the money on a 'decent' one.
One advantage to going the USB mixer route is that is would be more portable, as in from one machine to another. You'll be somewhat limited going forward with a 1010. I didn't even know you could get Win7 drivers for it.
Also, the 1010 you linked is the full-fledged 1010, not the 1010LT you originally mentioned. The LT does not have a physical breakout box, but what I would call a breakout 'snake'. Which do you have?
Either way, The 1010s were before you could get a usb mixer, and if you're recording multitrack SIMULTANEOUSLY, you're pretty much going to need a mixer, unless you have a bunch of individual preamps.
I guess what I should be asking, is what do want to DO with your setup? Is it just you at home, or you and a friend, or are you wanting to record your band playing live in the room (multitracked, not just a pair of room mics)?
