Android app compatibility was basically flawless once the Amazon Appstore was installed. I tried Kindle, Angry Birds, Twitter and few others — the only major flaws were that Android F33 Cell Phone apps continued to play audio at the lock screen if the tablet was locked or went to sleep while they were running, and the software volume control was impossible to access while in Android apps, which ruined a couple gaming experiences. And of course all the apps I ran were upscaled Android Eken M013phone apps; Amazon doesn’t actually have any Honeycomb tablet apps in its store. Fusion Garage has also built in several of its own apps, including a unified messaging client, a calendar, a custom maps app, a contacts app and a media player. All of these adopt the general Grid OS aesthetic, and they can also theoretically sync with external services like Facebook, Gmail, and Twitter, although I was never able to make Gmail sync work. The browser offers Flash compatibility, tabbed browsing, and a novel split-pane view that lets you browse two sites at once. It’s not the best mobile browser I’ve used, but it’s certainly passable. And it had better be: all of the other icons pre-populated on the Grid OS homescreen are really just shortcuts to various web sites.
