Yeah, and I can just see myself giving it a 2 minute charge then forgetting to plug it in at bedtime day after day... Or they could have put the plug at the back so you could use it while it was charging (like Logitech have done for years) and it would be just that little bit more magical... Its called the "Magic Mouse" not the "Adequate Mouse".
However, since the whole top is the "button" and moves when you click (looks like, on the Apple Wired Mouse, there's an internal wire that flexes when you click... yuk!) so you'd need a big ugly cutout to let the cable plug in to the 'base'. Still, form beats function yet again...
Mice and keyboards have moving parts which are likely to wear out long before a Li-ion battery that gets charged once a month. Come end-of-life, if the lithium is worth recycling you don't have to take as much care as iFixit did when you tear it apart. Also, the battery clips in the old Magic Mouse were a huge weak point.
I don't think you can do force touch on the Magic Mouse 2 - going by the teardown its still using a click switch... Meanwhile, the logitech MX Master has 6 different buttons to click and two scroll-wheels. I'm sure you'll be able to map a middle-button click to force click as soon as Apple decides what force click is for in OS X - force click is mainly useful in a touchscreen OS where you don;t have so many input possibilities.
Not sure why you'd need EDR for a pointing device or keyboard. More interesting would be 'Low Energy' mode which is part of BT4. The Logitech MX Master won't work over bluetooth with BT 2.1 Macs, either (but it can also use logitech unifying wireless dongles).
