All of these arguments perhaps point to the true reason no Linux device has really sold in massive numbers. There's an argument over even the minute of details or capability and compared to something mythical.

8 hours of device time, in full-blown use is not a bad metric. Not the best, but a 2kg laptop barely beats that. Most phones state high numbers, but use them for hours with screens turned own. You'll rarely get more than 5.

What's being called a toy, I use professionally. I use both the iPad Pro and a Surface Pro 4 in the creative industry. Both get more than 8 hours actually, if I'm being smart that is.

What's being touted as a solution; I don't think it exists. And this product won't address what you guys consider a solution either. Not sure what would - I didn't get 8 hours+ on my N810. Pretty darn close, but it's no longer supported - community or otherwise.
