I wouldn't consider the GPD Win in the same category because it was not designed to easily switch between being hooked up to a big screen or used portably. It's a palmtop computer with a controller embedded in it, not a hybrid. Being able to hook it up to a screen is an afterthought.

Performance is really a key factor, and gives rise to now being a time when truly competitive handheld is possible. Like this chart shows, there was a quadrupling of power between 2016 and 2020, but only a doubling of power between 2020 and 2023, with stagnation for the last couple years, largely due to technical limitations. RAM and storage have also seen massive boosts followed by stagnation, as well as a closing of the bandwidth gap between RAM and storage (from about 6 orders of magnitude to 3 orders of magnitude difference with solid state storage). The GPU front is still increasing in performance, with more watts and/or transistors giving more power, with raw performance increasing by a factor of 8 over 10 years.

Now you take those base values for performance, and a few things come together. First, storage has become low-energy, and is more performant, especially in the mobile market. Second, lower power CPUs are reasonably competitive, which means longer battery run time at an acceptable performance level. Third, while there is a bigger gap on GPU performance, smaller screens mean fewer pixels to drive so something a little older and less power hungry can still give satisfactory results. Put those all together, coupled with the steady and constant improvements in battery performance over the last 30 years, and you can make an acceptable mobile computer platform with decent results that's able to play all but the most demanding of games from the last few years. Certainly, you can't compete with the power of a desktop gaming PC, but you can get good enough. And then, with a few design tweaks, you can get a little better.

So, until and unless serious changes happen in the CPU or GPU market, mobile PC gaming has a chance to be good enough for a lot of people. I currently do over 90% of my gaming on the Steam Deck, but I'm also aware that I have little interest in playing the newest game as soon as it comes out so the Steam Deck is particularly suited to my tastes.

4.26 million copies sold, 17 best game awards and critical acclaim as the fourth best game for the 3DS disagree. The game also predates Breath of the wild by four years. I don't know anyone else who compares the two directly. The LoZ games had always, until the Switch, been defined as existing in two distinct lines, the handheld games and the console games. I was thinking more of games like Metal Gear Solid Snake Eater, Ocarina of Time, Splinter Cell, The Sims, or Resident Evil Revelations who were more direct ports. And that's even with a caveat, as RER was released for 3DS first then ported to consoles, and other ports were purpose made remakes that conserved the gameplay loop but were otherwise heavily adapted.

The 3DS has more that 1800 games, and most of them are exclusives.
