Windows-Based EFB

I'm finally conceding and having to go with electronic charts this year. With the number of EFB's out there, what's the recommendation for Windows based EFBs? Seattle Avionics Voyager looks interesting, but was curious as to other good recommendations.

I use Seattle Avionics as well, but the FlyQ system (computer, Ipad & Iphone) that AOPA sponsored originally. Seattle Avionics is close to releasing their new ATLAS computer based that I believe will link with the FlyQ on the Ipad and Iphone.
