Microsoft won't give up on the Surface because of failures of past iterations. No, it's intent on making an impression on the tablet market. As such, Microsoft revealed the Surface Pro 3 today.
It seems that Microsoft's primary goal with the design of the Surface Pro 3 was to do away with consumer uncertainty about whether they should buy a laptop or a tablet. That's because Microsoft wants this tablet to replace your laptop.
As far as specs go, the Surface Pro 3 will have models that feature Core i3 (starting at $799), i5 (starting at $999), and i7 (starting at $1,549) processors, up to 512GB storage, and up to 8GB RAM. The tablet has a 12-inch screen with 2160x1440 resolution, and is only 9.1mm thick. It'll be available on June 20 in the US and Canada.
