This article includes sales estimates for different handhelds from market research firm IDC.
They place total handheld PC sales of the Steam Deck, RoG Ally, Lenovo Legion Go, and MSI Claw at almost 6 million units for the past 3 years. It’s estimated that the Steam Deck makes up between 3.7 to 4 million of those sales, more than all the other major handheld PC manufacturers combined.
I have a couple of uses for my steamdeck. The vast majority of the time it sits in my living room. I use it while I’m watching TV with my wife. The ability to pick it up, resume whatever I’m playing right where I left off is great.
The other use is when I’m traveling. It’s smaller than a laptop, desktop mode is a fully functional Linux operating system, and it connects to any hdmi port with a small dock. That means I can use it to game, and connect it to the TV in the hotel room and watch whatever I want.
