Am I the only one who feels like Android is a step in the wrong direction? It's a PHONE OS. It simply cannot do what Windows does (or even Apple OS for that matter) as far as what I personally want from a device in terms of performance capability and security.
nVidia is not competing with a market, they're buying into it. With all of the AMAZING things they can do with graphics, it surprises me that they're willing to build on a platform that is 10 years in the past.
What are you expecting in terms of performance capability and security?
Android's advantage is its vulnerability--a "free" and "open" (yes, in quotes for a reason--it's neither free nor totally open) OS that "anyone" can put on a device. You're not locked into one device manufacturer, so it properly fosters competition. On the other hand, you're at the mercy of whomever you get your device from, and no one is really making any efforts for equal user experience or security across the entire "android" platform. But I would not call it any less secure or incapable of delivering performance than iOS. On the contrary, I think 4.1+ is quite a bit ahead of iOS in very many areas.
Relative to windows tablets, which are more-tuned for productivity, android faulters. While they can be used for taking notes and composing documents, most android tablets have horrible user experiences for productivity. Google Doc's (Drive) is actually pretty good for document creation and editing, but it still requires an internet connection on Android. But I don't think android tablets are typically marketed as productivity devices, so those who buy them are already knowledgeable of this point, and generally use them as mobile media consumption/entertainment devices.
Though I didn't buy one, I'm hopeful for the next revisions of MS's surface tablets. I think bay trail atoms will be a great addition to this space, and I think Surface RT (if it does get a refresh), will benefit greatly from the improved SoC's after Tegra3 (which was another lackluster release). I think Surface can be the proper marriage of entertainment/media as well as productivity. Just get rid of that dumb goddamn kickstand and magnetic base attachment, and get a proper docking keyboard with a secondary battery.
