We have pretty darn fast internet at home - I am on my home computer and run windows 7. Don't know if that makes a difference or not. But when I click on the link to go to the marketplace, my screen goes white as its trying to load, but just sits there and nothing happens. darn.....
It's loading slow for me. Really slow. I'm thinking "opening day jitters" is going on. Hopefully they'll get that resolved fairly quickly.
