I have a mouse cemetery in my office cabinet – the devices I tried and discarded because they didn’t help with my shoulder pain. The solution is the roller mouse, and Logitech’s MX Ergo is the best I’ve found. It tilts a more natural “handshake” grip and has a slow motion option for more precise movements in Photoshop and other apps. The rollers are fast but precise, and so are the trackballs, you can switch between the two devices using the pairing buttons. You can even program various buttons using Logitech’s software to perform application-specific operations. It is also a convenient companion for iPad and can also make good Mac accessories.
My only wear is the outdated micro USB charging port, but the battery lasts long enough that I only need to use it every few months. It’s $100 expensive, so you might prefer the $70 Ergo lift. It also offers handshake grip but no roller and has Bluetooth or USB dongle connectivity options.
Of course, there is Apple’s own magic trackpad, which basically copies the touch surface of your MacBook, so you can place it anywhere. If you are a fan of multi-touch gestures on your MacBook, this may be a more comfortable way to use them. – as
