Both the iPad 2 and the Galaxy Tab 10.1 can triangulate your location based on Wi-Fi signals and GPS. The beta Navigation app that comes with Android is a much better navigation app than the Maps app that comes with the iPad 2. On the iPad, you'll want a real navigation app such as the $45 , whereas on the Galaxy Tab 10.1, you could stick with the free one -- as long as you don't need the map display itself to be updated while you drive (that would require 3G connectivity).

Although both the iPad 2 and the Galaxy Tab 10.1 ask for permission to work with your location information, the Galaxy Tab does not provide controllable settings for location use by the device or individual applications, as the iPad 2 does.

The Galaxy Tab 10.1 wins this round, thanks to its superior navigation app.

It's often a throwaway comment that Apple's UIs are better than everyone else's, though it's not always true, as evidenced by the soon-to-disappear MobileMe service. But the iPad 2's in many respects, allowing easier and faster access to the device's capabilities and information. Where the Galaxy Tab 10.1's Android 3.1 OS outshines the iPad 2 in terms of UI is through its widgets and notification capabilities, as previously mentioned.
