well I mean, 4x range bumps it to over 100 ft, where as it used to be 30 right? (Or am I just out of date?)

But lag and dropouts is definitely my same concern with Bluetooth as well..

That said, it's still my preference if only because it's a standard - but it's getting damn hard to find decent Bluetooth mice now

4x range also may mean you get interference from 16x the number of other devices. In a frequency band where everyone and their dog broadcast (https://en.wikipedia.org/wiki/List_of_2.4_GHz_radio_use), that may not be a net win.

"4x range" means the marketing guys could say anything they wanted. Just like how 4G LTE is multiple Gb per second, 10 times faster than the previous generation! :D

Bluetooth can already do 100 ft... in very good conditions and with the rights devices and drivers.
