Yep! I have a Jabra headset and I picked up a fancy newish Razer mouse that uses 2.4. Very odd system interrupt behavior slows the whole system down. I changed the mouse over to bluetooth and the problem goes away. It's not as EXXXXXXTREME as using 2.4 on the mouse, but hey - the system isn't so laggy now.
Interesting. I ended going back to 2.4 on my mouse as I'd have all sorts of problems with a Bluetooth keyboard, mouse, and headset connected simultaneously (on a Macbook Pro).

I had a similar problem, and it turned out, I think, to be Bluetooth congestion.
I was in an office that was partially a call center, so lots of people on Bluetooth headsets. Plus all their mice and trackpads. Plus their keyboards. Plus regular headphones. Plus plus plus.
My desk faced out the window onto a public street. Very often, when a group of people would walk by my window, presumably each with his own Bluetooth devices my trackpad would disconnect from the MacBook.
The solution was to keep the trackpad plugged into the machine, since I never took either anywhere anyway.
I've been seeing the mouse/keyboard issue at home, mostly.
But I'm reasonably sure I've also experienced the Bluetooth congestion issue in a different context. I have an old, mediocre Bluetooth head unit in my car, and it disconnects from my phone ~90% of the time I drive in traffic. Works flawlessly on back roads and the like.
What? Bluetooth is 2.4Ghz. I guess it's just a proprietary 2.4Ghz radio protocol (Nordic Semiconductor low-latency proprietary I guess) vs Bluetooth (on 2.4Ghz).
Something like that, correct. According to the tech specs you have "Razer™ HyperSpeed Wireless" and Bluetooth as options. The hyperspeed thing is what causes system interrupts out the wazoo.
