I'm looking for suggestions to replace my "ancient" Apogee Duet. I'm interested in something small, simple to opperate (not a lot of extraneous features), durable (i.e. without a lot of fragile knobs and buttons), reliable, and (it probably goes without saying) a good, clean sound ... to serve as my portable/travel audio interface. I probably don't need more than 1-2 inputs and stereo output ... though 4 outputs might be nice, if the overall package size was still compact. I've only ever used 16-bit/44.1 kHz audio in a concert setting in case that expands the possibilities ... and I'm becoming an "agnostic" on the firewire/usb debate.
And ... a corollary question: Is there some reason that there is no support for RME interfaces ... like this one:

Several of my non-Kyma friends who do a lot of traveling with their audio interface swear by this company's interfaces, especially their "babyface" interface.
