Geolocation is supported, which allows TripAdvisor to quickly locate places nearby. But while that's a neat feature, it's also a bit of a downer -- because, really, it's about the only feature TripAdvisor for WP7 brings to the table that its mobile Web app doesn't already offer (its browser-based geolocation doesn't work with WP7 at the moment).
While it's nice to see Windows Phone 7 users getting some big-name apps, it'd be even nicer if we saw some packing a bit more swagger.
Still, TripAdvisor for WP7 might just be worth installing on your device if you're frequently on the go -- at least until a better browser arrives with the Mango update.
