I tested the MX Anywhere 2 with both Mac and Windows laptops. I like it a lot, though ergonomically speaking it isn't as comfortable to use as the MX Master. That said, it's about as comfortable as you can expect from a smallish mobile mouse that's designed to easily fit in the side pocket of your laptop bag. And it's a nice weight at 3.7 ounces (105 grams).
As you might expect from a high-end mouse, it has plenty of bells and whistles. Thanks to Logitech Darkﬁeld Laser technology, it works on just about any surface -- everything from a glass table to the Formica-style finish of my work desk.
It has an integrated rechargeable battery that's supposed to last up to 60 days on a single charge, which is almost double the battery life of the MX Master. You can continue using the mouse while charging with a Micro-USB cable, and just 1 minute of charging gives you 2 hours of usage. I wasn't able to precisely test battery life, but I haven't had to recharge it in the three weeks I've used it.
Like the MX Master, this mouse can connect to your Windows or Mac computer with the included Pico Unifying Receiver (a small USB dongle that will also work with Logitech keyboards) or via Bluetooth Smart technology.
If you go with Bluetooth, you can pair the mouse with up to three devices and switch between, for example, a laptop, desktop and tablet using the appropriately named Logitech Bluetooth Easy-Switch button.
