MICROSOFT loves to compare competitors' real products to products that it has not even released yet (and therefore cannot be benchmarked reliably). Microsoft uses draconian terms in the EULA to prevent parties from conducting and publishing benchmarks. False performance claims are currently being spread around by Microsoft, touting the speed of a product which is not even out in the market.
That was the answer to your question. “Is it really fair to be bagging on something that’s not even released?”. Yes and no. Normally no, but when Microsoft is already lying about it being faster than the speed of light on a day that God did a line of coke, I’d say they made the damned thing fair game already.
