Really wish people remembered to put USB pass-through on their keyboards though. If I need a small form factor keyboard, it's gonna be a good bet the number of USB ports available is at a premium and chaining will make life so much better. Depending on what I'm doing, I'm going to need the zero latency of a cable (like using my keyboard with FL studio to make some music, for which Bluetooth latency -even the latest gen- is still way too high)
It does when it's also possible to use as a corded keyboard though. I'm not going to use Bluetooth if I have the option to cable (in part because "why would I use wireless when I don't need to" but mostly because I'm also going to use it as a fake piano and even the latest generation of Bluetooth still has unacceptably high latency for virtual instrument feedback)
I just upgraded from kinesis advantage to 2 and was bummed they removed the USB ports. My mouse got better wireless connection when plugged into keyboard than into laptop sitting back of desk.
