The decision to go from Unifying to Bolt is mystifying to me, since there's seemingly no user-facing benefit. It makes upgrading less enticing -- they should have either rolled out a new set of peripherals that all supported Bolt at the same time, or they should have rolled out an interim generation that supported both Bolt and Unifying.

Isn't the Unifying encryption broken beyond recovery or something? Either way, more secure connections for something as critical as input data are very welcome IMHO.

That being said, for office work I'm satisfied with Bluetooth. No extra dongles is a huge plus, too.

At first look, the Bolt stuff is supposed to be more secure, with better encryption or the data transferred and maybe with narrower band to allow more concurrent users in high density offices. I don't know how much it is correct and how much it is marketing, this is what I read.

The Unifying used same frequency as BT but a diferent protocol.. The Bolt is basically BT 5.0 Low Power..

Also, no USB-C? I now need to plug my Unifying Receivers into a dongle to go into my M1 machine. Yuck.

I bet this is why the release a MX Master 3S as an minor update to the previous MX Master 3.. that only have bolt option..

I still have an MX Master 2 and i am considering getting this as a bundle, MX Master 3S and MX Mechanical..

For keyboard i currently have their G512 gamer and it bother me that it use a separated software from the MX Master 2, the keyboard use the Logitech G Hub while the mouse use the Logitech Options..
