Google’s new Android Market has arrived on the Samsung Galaxy Tab overnight, complete with a refreshed UI – including a Cover Flow style app carousel – and new categories for Widgets and Live Wallpapers. Announced last Friday, and expected to roll out to all Android 1.6 or above devices before December is out, the new Android Market also flags up related content.

One controversial decision on Google’s part was to reduce the refund period to fifteen minutes, meaning buyers who accidentally purchase an app now have less time to return it. Still, overall it’s a marked improvement in layout and usability over the previous version.
