If this device gains traction... which I think it could... it spells the death knell for other Android tablets, no matter their superior size, quality or specs. The price point won't and probably can't be matched. And even it could, Amazon at some point could again make it free i.e. subsidized to sell their services and merchandise. It's the ecosystem... and as others above have mentioned, it's a AA game, not AAA at this point.
I continue to say that Android, as it is is today being open for any and all, being actively developed by Google first and foremost... will cease to be by next Summer. For various reasons, but this news just adds to that inevitability. They will concentrate on Chrome, and let Android and all of it's assorted forks flounder on their own.
Only horse in this race that still isn't even out of the gate, is MS. I as well as many here deride Balmer as a buffoon of the tree-swinging, dev-dancing, chair-throwing tantrum kind. Just imagine if MS and Ballmer are not as dumb as they appear to be, and are biding their time and watching how this all unfolds (implodes?) first, before jumping into the race. It remains to be seen if Ballmer has a trick up is sleave and is a jockey, or just plain joke.
Let's not forget: it took MS 4 (5?) versions of DOS/Windows before they were on a par with Apple when it comes to "consumer" and user friendliness. "Par" is up for debate... I know. However, these devices demand user-friendliness this time around. There's a lot of people impressed with Metro. I for one, if only because it's an original instead of a copy of Apple's iOS. It will be interesting how they integrate it with Win8.
When I view my personal crystal ball into 2014, I see Apple still in the lead; Google stumbling badly on turn 2; RIM has been Medivaced; and MS pulling around the turn with speed to nip at the tail of our beloved unicorn

PS: Have I ever mentioned I'm a betting-type of guy?

PSS: ... and NO! I do NOT like MS or any of their products. However when betting, you really should stay objective and detached from emotion.
