TL;DR: This mouse is, in my opinion, a huge improvement over the Performance MX.


I just recieved my Master MX mouse, here are my initial impressions. I have been using a Performance MX for a while, I will be comparing the new mouse to that.

Feel: This thing feels much better than the Performance MX. The arch of the mouse is a bit higher than the Performance MX, it seems to fit my hand a bit better more naturally. The textured area around the thumb is a nice added touch as well. The forward and back buttons are going to take some getting used to, they are moved back towards your hand a bit more. Still a nice feel. The new thumb scroll wheel

Left and Right Clicking: Seems a bit easier to click compared to the Performance MX.

Scrolling: This is a part that I really like. The Performance MX's scroll wheel had the two settings: free scrolling and the clicked scrolling (not sure what else to call it at the moment) that you could toggle between using a mechanical button which would switch between the two settings. On the Master MX, these two scrolling methods still exist, but the new software (see below for more) can automatically detect your scrolling speed and switch between the two. For example, if you want to go line by line, you can scroll with a slow speed and you will get the clicking feedback on the scroll wheel. If you want to scroll to the bottom of a long webpage and flick the scroll wheel, the mouse automatically detects the speed and will engage the free scrolling mode. A nice added touch, in my opinion. The two modes on the Master MX can also be toggled using a button in the same place as the Performance MX's. The scroll wheel, however, does not go left and right like the Performance MX.

Software: Logitech has finally updated the connectivity software. It looks nice. I haven't messed around with too many of the settings, but here are a few screenshots of it:

Gesture customization. The thumb button can be used for gestures. Hold the button and move the mouse up, down, left, or right to do different actions.

Few other things: The batteries are integrated into the mouse; can't change them as easily as the Performance MX's (although they are still rechargeable). I know this was pretty disjointed, but just wanted to give y'all my initial thoughts! Lemme know if you have any questions

Will the new software work with an older mouse - like the Performance MX? Or do you need to keep the older LCC installed?

No, the new software is for the K760 keyboard and the MX Master. You'll need the LLC for the old Performance MX
 
According to the Logitech site, the new Logitech Options driver (which is just Logitech Control Center 5.0... the old one was 4.5) is compatible with the devices listed below. Essentially, any of the recent bluetooth enabled keyboards and mice/trackpads will work with it.

Bluetooth Easy-Switch Keyboard K811
Bluetooth Multi-Device Keyboard K480
MX Master Wireless Mouse
Rechargeable Trackpad for Mac
Ultrathin Touch Mouse T630
Ultrathin Touch Mouse T631 for Mac
Wireless Solar Keyboard K760
 
i'm curious if you can comment on the dreaded logitech coil whine. Basically put the mouse to your ear and see if you can hear a high pitched sound.
