Is this the end of Kindle?

If you didn’t notice, Microsoft has made a familiar move and now owns a significant share of the Barnes & Noble Nook. The word is that a Nook hook will be in future versions of their dominant operating system and I wouldn’t be surprised if in a further move, Microsoft might take full control of the Nook and maybe even Barnes & Noble itself. The arrival of Microsoft on the eBook scene caused investors to almost double the price of the B&N stock. I suggest that Amazon teach that pony a few new tricks if they want to stay in the game.
