> With 24-hours per charge on a lot of these modern laptops, why do you need to carry spare batteries?
At least for ability to quickly poweroff my laptop, for example if OS is hanged down or maybe if some water spilled on the device. Also I do not want to carry laptop to a service just to change battery. Last but not least, internal batteries use to be unique per model while external batteries use to be a mass product, good luck finding spare internal battery for really old laptop.

The main reason of my hate to all kinds of external hubs is that when your mobile device has a beard of hubs and adapters then some of that connections are going to lose a contact mechanically. Why not just to drill more holes in the side edges of device instead of making side edges empty?
And you told nothing about where to get a modern laptop with as comfortable keyboard as in my x220.
