Holy shit, how can everyone be so wrong? This is their best product:

- Indestructible
- Wired
- Moves effortlessly
- More accurate than a mouse in competitive FPS
Maybe you disagree on all of these. That's fine, but when you feel what it's like to scroll down a long-ass PDF with one of these bad boys you'll never go back to a mouse. Bind that little silver Back button to toggle scrolling and let it fucking rip!!!
I'm also partial to Logitech's "Unifying Receiver." They're just a tad larger than a USB-A plug and can be paired with a number of their products (mice, keyboards, touchpads, etc.) Also: unofficial Linux support. They're better than shitty Bluetooth adapters by a mile. The aforementioned K-400 keyboard + touchpad is a must-have for any HTPC/couch setup IMO, although the other poster is correct in that "Plus" model feels like a downgrade.
One thing I like about Linux is that there's almost never official software for controlling peripherals, so inevitably someone will come along and write software that works 100x better than the stock software on Windows, with the only downside being that it looks like total shit. It's really something.
