Just out of curiousity, regarding GPS performance on the Fascinate: On the Engadget Epic 4G review, they mentioned that Samsung told Engadget this:
"Google is now requiring that the "use wireless networks" setting for location-based services be turned off by default in Android devices -- in other words, no AGPS unless you manually enable it. Sure enough, we went into Settings, found that it was disabled on the Epic, turned it on, and we were good to go."
I wonder if all the reviewers are actually turning on AGPS before testing GPS performance...
