Update: It's still down for us on a Froyo Nexus One, but if you take a gander through our comments section, you'll see that a lot of folks are having no trouble at all -- so it's probably based on your location, your devices, and your operating system. As far as we can tell, it's not restricted to Froyo since we've received a number of tips on the issue and we're hearing of some Droids that can't see apps. Keep the observations coming, folks!
Update 2: Google just reached out to us to let us know that it should be fixed and that the total outage was somewhere in the neighborhood of 30 minutes. They're apologizing for the inconvenience -- but with the Droid X being announced today, can you really hold a grudge?
