Haha, I was just going to ask about Bluetooth. I've got 9350 and while single device Bluetooth works quite well (okay, today it broke but it usually works) connecting Bluetooth headphones and a Bluetooth mouse at the same time makes the connection super unstable. That's with the proprietary firmware.
There are all kinds of issues in XPSes as far as I've seen. But generally it works well on Linux. I mean the same issues plague Windows too (I compared).
I have given up on bluetooth ever being sane. If I don't connect my JBL, my xbox remote or anything bluetooth for more than a week then the connection is kapput and I have to delete and re-add the device. Windows, Linux, doesn't matter. It magically stops working when not used enough.
