Unlike the Microsoft Surface, Google shows competitive mobile products can be co-developed with OEMs--even when you are providing them free open source software.
I'd love to hear any insider details of how the collaboration went.
Check the specs: GPS is included.
I'm not prepared to do a side by side comparison with Samsung offerings. Judging only by the introduction at Google I/O, the Nexus 7 looks pretty cool (of course, everything looks cool when it is being introduced at an event like this). I would say the Nexus 7 is going to be some stiff competition for the Kindle Fire. As for the iPad, I think the price points and the features put them in different categories. But if Nexus 7 is as advertised, I have to believe it will give people who were thinking about buying an iPad an excuse to spend a lot less money.
Competition will never stop coming. The price of Nexus 7 is very attractive. It poses highest threat to Amazon Kindle and B&N Nook Color. They are both 7".
Interestingly, GPS is not one of the features. I wonder why.
