Personally, I would do just like @AntonyTerence did - make another comment to add something because that way people get to know you commented again (if you only edit, people who've already read the comment won't get to know you added something). Only when I've remembered something I would like to add right after I comment I edit (or if I made some mistake).
Nevermind, regarding these two points...
The Intel North Cape Project would have to be something to be explored by the Eve team in China, when sourcing components so I'll tag @Konstantinos. I think its a good idea that can add for the pf's USP. For example, reviewers would obviously talk about this feature, immediately influencing the informed consumer's perception of the device - this 2 in 1 tablet is going to be directed to the informed consumers/tech enthusiasts/maybe businesses since the brand isn't that well-know and as such the "mass" market will be IMO a difficult target to reach, as the OnePlus was in its first edition; tech people were stoked about it but only one of my friends knew about it (he ended up buying the OP2 BTW). That's why it's so important to advertise this device in every place you can encounter (real or virtual) - the consumer needs to know about this device.
The removable m.2 slot would be great since the target market is the one I expressed above. Why would you want an HDD when you can have a SSD?
On a side note, I think we should also make a competitor to the Surface Book (with a dedicated graphics card and core i processors...) to blow the high-end market also since this device is primarily focused on mid-end with many high-end features. I think in the above stated project, money shouldn't present a limit - just put the best components in their category. It would be a powerhouse of a device and some of the areas we could direct this device could be gamers (they could boast a powerful, portable and light-weight device for gaming on-the-go), graphic designers (that do 3D modelling and other highly-intensive tasks) and developers (game developers and people who develop x32 apps for instance).
