Well I’ve got a power strip so I’m not running separate power cords for my computer, a powered USB hub, a lamp, an external hard drive, etc. since that would need a whole bunch of wall outlets that I definitely don’t have.
Having more than two things plugged in at a desk is pretty common situation and literally everyone solves it with a surge protector / power strip. So the laptop cord isn’t dangling across the room, it just runs from the power strip under the desk up the wall to the laptop on the desk. Not a situation where MagSafe would do anything for it.
There are well setup home office desks (I use one, now, didn't always have one), and there are all kinds of office makeshift desk situations, from a simple small ikea desk with a laptop on it and not much else, to the kitch table used as a desk (and cables going to the wall).
Sometimes you're also on the sofa and need to charge, and so on...
Right, but my point in the original comment is that with a 20 hour battery life you wouldn't have the "on the sofa and need to charge" problem anymore.
