Ergodex, makers of the DX1, haven't updated their drivers in over a year. And when asked about updating their drivers, they pretty much suggest buying another product. I love the DX1 but had to move to Vista for work so I can't use it anymore. If you are on Vista or planning to upgrade stay away from the DX1. Unfortunately I don't think the company is developing anything at this point.

The CH MFP from here: http://www.chproducts.com/ is the same thing as the DX1 for $60-70 more, but it has updated drivers for XP and Vista.
