I did find that intel has announced a 15W quad core i7 for the 8th gen i7. It promises a 30% increase of performance over the i7 7500U. So it got me thinking. I want a quad core 2 in 1 and maybe this could be the quad core that solves my problem. As I have read on the Eve V m5 performance thread, the Eve V could decently cool the m5 on a TDP of 15W. So how about a big brother for the Eve V? I like my laptops at 15"-17", I think a 15" big V could easily deal with a 15W quad core (maybe even let you raise the TDP a bit) with passive cooling. I would suggest that there would be 2 options, either a simple pogo-pin keyboard just like the Eve V has (with bluetooth) and the other option is a keyboard docking station (such as like the surface book) with a dGPU and extra battery and extra ports. Maybe a third option would be a desktop dock.
For that docking station I would go with just a 180 hinge, the connection with big V through a thunderbolt port (or 2 thunderbolt ports, 1 for the extra ports and battery and the other for the extra ports). It could either be a U shaped holder to insert the big V which has centralized thunderbolt(s) port(s). You can use it as a laptop with touchscreen than, or flip the big V around so you use the base just as a holder to stand the big V up, or use it like some 360° are set upright, using the base as a big kickstand.
The other way could be that the holder hinges like the acer aspire R7/R13. Than the thunderbolts should be on the opposite side and integrated in the hinging part. this way you don’t have to disconnect to big V to swivel it around, although this is harder and probably more expensive. So would be cool but largely unnecessary cost. Extra ports should be at least a ethernet port, regular HDMI and display port (not those mini things), probably extra usb ports (I sometimes don’t have enough with my 3 usb ports on my laptop).
And for the desktop dock: a bit like the keyboard dock, with a U shaped holder to insert the big V in, it automatically charges the V than and it could double as a eGPU dock and it could also have an integrated fan to cool the big V’s backside.
That is what came to my mind, and thought about sharing. It would be in line with the Eve V, it would provide decent performance, many things from the Eve V could be reused but scaled up. Also, more space so bigger battery possible. I think 15" is about right for a laptop with performance, 17" is nice for its extra space, 13" is on the small side for me, it could be fine but I prefer bigger screens than that, so that’s why I propose it with 15" and not another size, but I do know that there are many views on ideal size, so don’t focus on that part, it is more about bigger than V and better than V
