Yeah, it looks like the manufacturers of generic tablet accessories are prepared for the Jolla tablet to appear. A search for "Jolla Tablet" under "electronics" in Amazon is giving me 379 hits (although maybe a third of them are for "La Jolla Cove"). Lots of covers, keyboards, styluses, chargers, and memory cards specifically mentioning the "Jolla Tablet". I would imagine they might all work, too, though they can't have possibly tested any of them.
