Merry Christmas and Happy Hannukah, Kindle sales seem to be the stocking stuffer as other devices lose market share. "Kindle device and book sales will total $1.6 billion for 2010. That's 5% of Amazon's total sales." Sell the device and build a store to deliver content. Amazon is emulating the Apple App Store and taking advantage of changing trends. Can Barnes and Noble and Borders survive as they have been slower to adapt.
I currently don't own a Kindle and keep waiting for a device that provides color as well as black and white content, in an easy to hold, light, and nimble device. Perhaps my hesitancy reflects others that have not become early adopters. I do believe the company that delivers this device first will ultimately win the war. I expect the Kindle folks are working furiously to build such a device so the others better hurry.
