I bought a Steam Deck! I would've got one much sooner, but they still aren't officially available in Australia. I finally found a good importer and picked up the OLED 512 GB model.
I'm extremely happy with it. Right off the bat, I was struck by how great the ergonomics felt. It fits my hands near-perfectly. Heavier than the Nintendo Switch, but not too heavy.
Performance is good - comparable to my aging GTX 970. Having that in such a small form factor seems amazing.
