The Steam Deck went on sale on February 25, and the creators decided to showcase early design concepts for the device.
The photos below show the evolution of the handheld PC. Ultimately, the company chose a design that does not look like the Switch with Joy-Cons.
It is worth noting that the photo shows white, red, and orange color options. Currently, the Steam Deck is available only in black. Perhaps Valve will expand the Steam Deck lineup.
As a reminder, Valve previously reported that it would create a Steam Deck 2. Given the time spent developing the device, it is no surprise that the company had many different ideas and prototypes for the handheld gaming PC.
