Fusion Garage said it’d be back, and here it is.

Fusion Garage recently announced a tablet and smartphone, dubbed Grid 10 and Grid 4, respectively. They’re both powered by Fusion Garage’s signature GridOS based on the Android kernel.

The OS “reinvents touch computing from the ground up,” according to the Grid 10 product page and is completely gesture-based as opposed to the four-button design of straight Android tablets. In a further step away from other Android devices, Bing is GridOS’s default search engine because it is “the better of the two search engines,” according to company head Chandra Rathakrishnan.

Fusion Garage is perhaps best known for its floptastic JooJoo Tablet, which debuted shortly before the iPad shook the tablet universe. Although innovative and sleekly designed, it lacked battery life, an app library and was generally buggy. It was so thoroughly lame it earned a spot in our Worst Gear of the Year 2010 roundup.

But the Grid devices’ specs sound pretty good, at least on paper.

The Grid 10 is, not surprisingly, a 10-inch tablet. Its claim to fame is having the highest resolution of any tablet on the market, 1366x 768. It’s got an Nvidia Tegra 2 chip and 16 GB of storage, with a 1.3-megapixel front-facing cam and baked-in video chatting software. It’s also Bluetooth enabled. It ships with Fusion Garage’s own app store, but will support Android apps.

The Grid 10 will run you $499 for a WiFi-only model and $599 for WiFi and 3G. It begins shipping Sept. 15.

The Grid 4 has a 4-inch 800 x 480 display and is powered by a dual-core Qualcomm processor. For $399, unlocked, it comes with 16 GB of memory, an 0.3-megapixel front-facing camera and a 5 MP rear-facing autofocus camera. The shipping date is TBD, but the company says we’ll see it sometime in Q4. Carrier info will come as we get closer to the release date.
