On the topic of laptops, while this might change once reviews flow in, I think the 2060 is probably going to be the value sweet spot, much like the 1060, although to a greater degree here. Why? 

• It's among the most improved in the Turing lineup, with a claimed up to 50% improvement over the 1060. The 2070 has a claimed 30% jump over the 1070 by comparison. However, the 2070 is still beefier, albeit perhaps not to as great of a degree as the 1060 vs 1070.
• Many laptop displays are 1080p. A GPU in the class of a 1070 will usually have zero issues driving a 1080p display at a high framerate, so performance isn't much of a concern in that context.

I still think there is a spot for the 2070 and 2080 for laptops, specifically those for bleeding edge machines, large desktop replacements or those with UHD displays. But I think for many, especially those who don't want to spend more than what's already expensive on a laptop, I think the 2060 fits the bill really well, much like the 1060 6GB did for the Pascal generation (although 1070 laptops are now in a similar price range to 1060 machines when they were new)
