It’s called the Google Pixel C, and it should be available in time for the 2015 holiday season for $499 and up. You’ll almost certainly want to spend an extra $149 to get the optional keyboard though, because the Pixel C is very clearly designed to work with a keyboard. The C stands for “convertible.”
The tablet powered by an NVIDIA Tegra X1 processor, features 3GB of RAM, and will be available with 32GB of storage for $499 or 64GB of storage for $599.
This does look like a fast tablet with a nice keyboard cover. But, I feel 32-64GB of space is too little space for a $500-600 tablet. I think it should at least have 128- 256GB of space.
Good keyboards like Gaming and Mechanical keyboards are sometimes expensive because Mechanical Keyboards last longer and more comfortable to use than cheaper keyboards. But, I think this keyboard is expensive unless this keyboard is a mini-mechanical keyboard which is made to last a longtime, and is more comfortable to use.
