Both the Apple App Store and Google Android Market separate tablet apps from smartphone apps, simplifying the search for appropriate titles. The Apple store also indicates which apps auto-adjust for the iPhone and iPad, so you know they can be run on both devices and appear native on each.
Unlike Apple's App Store, the Android Market is not curated; developers will have an easier time getting their apps listed, but the market also that masquerade as banking programs, games, or other apps and steal user information. to such Trojans. The Android Market is also not as easy to navigate within the app details, though it is extremely clear about what permissions each app needs to run. The Android Market does have one highly useful feature that the iOS App Store does not: an option for each app to enable auto-updating.
You don't have to use the Android Market to get apps onto the Galaxy Tab 10.1, of course -- unlike the case with a non- iPad. If you want to get down and dirty, you can configure the Android OS's application settings to install ("side-load") software from other sources.
Installation of apps is similar on both platforms: After selecting an app, you confirm your store account information and wait for the app to download and install. Both mobile OSes let you know if updates are available. On the iPad 2, the App Store indicates the number of available updates. On the Galaxy Tab 10.1, with those apps for which you've not enabled auto-updating, available updates are displayed in the notifications pop-up at the bottom left of the screen.
The Galaxy Tab 10.1 uses the Android Market to remember your paid apps (though not your free ones) and a separate sync utility for handling media files transferred from your PC, but in this regard it's no match for the iPad 2. Thanks to the iPad's reliance on iTunes as its command center for corralling media, apps, and documents, the iPad makes it much easier to manage your device's content. If you get a new phone, it's a snap on iTunes to get it up and running with the same assets as before. There's no such easy way to transfer the assets to a Galaxy Tab from a previous device.
