GUNNAR Optiks Cyber
These protect my eyes from the high frequency photons constantly emitted by computer screens. Even with a lower color temperature set on the device, these help immensely, especially when programming for long hours. They are comfortable and decently durable considering their lighteweight design. The temples are attached by integrated pressure springs.
The cylindrical wooden case from Ocean Reef is a great bit of armor for these, so I can drop them into my go-bag no sweat -- my wife got it for me as a gift since the glasses only came with the microfiber pouch, and it is wonderful.
Crucial X8 1TB External SSD
This external SSD holds my main media library on an XFS partition and a 250GB Windows Partition which mostly exists to play Phantasy Star Online 2. Read and write speeds are excellent with this device, and it's exteremly rugged and portable.
Western Digital Passport 2TB External HDD
Backups go here. I use kyanite to backup home directories and my media library onto a LUKS encrypted XFS partition with redundant files hard-linked to save space. It stays inside of a small cardboard box amidst some tissue paper to stay safe and cozy.
Afterglow Wired PS3 Controller
My favorite game controller is this cheap biz from Afterglow. It's comfy, responsive, and it's lasted through some travelling and traumatic drops. Great for all kinds of emulators, and PC games which don't support it natively can use tools to remap it to key/mouse input or map it to a virtual XInput controller. It's wired, so no batteries required.
I scored these headphones in the student store at UC Davis and I loved them so much I bought a second pair when I lost the first. They're very comfortable, the sound quality is great, and they work well for hands free calling and voice chat for gaming. I even used them when I worked in IT support over a real over-ear headset.
I store them in an old tea tin.
