It's still a long way from a full-fledged app store, but the Amazon Kindle has just taken one step in that direction with its very first premium app: Electronic Arts' Scrabble. That's available right now for $4.99, and it'll work on both the second and third generation Kindle, and both Kindle DX models. It also looks like it's already off to a strong start in terms of sales -- it's currently sitting at number four on the Kindle bestseller list, right behind two Stieg Larsson novels and the latest Oprah book club pick.
