Amazon Has the Kindle and Barnes & Noble the Nook...So What About Borders?

We've all heard about the Kindle. And most of us know about the Nook. And while Borders is not selling a dedicated eBook reader of their own, they have just doubled down on digital distribution.

While Borders already sells electronic books (in ePub format), they've bought a fair chunk of eBook retailer Kobo. What's this mean? Well Kobo distributes, not just to eBook readers, but to the iPhone, Blackberries, Palm phones and Android handsets.

And though Borders has not yet announced plans to distribute books through smartphones, their money speaks differently.

Also something odd to ponder: most of Kobo's 2 million titles are free. [Kobo via The Register]
