Hagerman HagUsb vs M-audio Transit - anyone yet?

Anyone has experience with HagUsb yet?

Currently I'm using M-audio Transit, and although I'm pretty satisfied with it, I was thining about trying Waweterminal U24.

I found out U24 got discontinued, but found out about this new product HagUsb. It functions almost same as Transit but with coaxial out instead of optical out.

I heard somebody said HagUsb doesn't support PC? but they say "HagUsb is compatible with both Windows XP and Mac OS-X." on their website.

I'm wondering about the performance, easy of use, compatibility with PC, reliability, etc. especially compared to M-audio Transit.

Thanks.
