Optimized for netbook resolutions, the AppUp Store serves as a central hub for discovering new apps for Windows. Since one of the primary issues of netbooks are small screens, the AppUp store provides an ample list of resolution-friendly standalone apps (i.e. not running on your browser) such as Facebook and TweetDeck.
If you’re running a netbook, it’s definitely a worthy download. But even if you’re not (I’m running it on a MacBook Pro + BootCamp), it still works on any WIndows XP / 7 enabled computer! Even if the app resolutions are optimized for netbooks, some developers have gone the extra mile to make their apps compatible with higher native resolutions.
