USB interface that works with Mac and W7 (on a bootcamped mac book pro)

I am looking for some feedback on a small 2 input interface for use with logic and sonar on a dual boot MBP.

I noticed Cakewalks UA 25 will work with both, but the fine print states there is no support for windows on a mac (does that just mean technical).
I know a few people are using mpb's and sonar, so what interface solution works for you?
