Amazon has a few things up its sleeves lately including a stellar mp3 store, a cloud player for that music, an on demand video store, and the Kindle platform for e-books. It would only make sense that Amazon would put all of those together along with its Android App store and build a tablet that could compete with the iPad2 and others. According to an Engadget report, it appears as this will appear at the end of the year. An estimated 700,000 tablets per month are expected to be ramped up by a firm name Quanta. Should Amazon build a tablet? Can it compete with the iPad2 and others?
