I think it's great seeing other company's ship Steam OS I exclusively only play games on my OLED Steam Deck since I bought it. Just simple download and play no issues but I am a outlyer I haven't used Windows in 15 years only Linux.
It's night and day different isn't it? That 90hz display makes a larger difference than I expected as well, my partner's oled deck is way smoother looking on top of having nicer looking visuals (I'm a sucker for HDR). LCD is still an incredible device, especially if you get it at a discount like I did mine ($475 CAD all in is amazing value), but if you can afford an oled one, it's totally worth it.
They have oled refurbs now, which I'd totally do having had mine apart to do a clicky button mod, it's really easy to get into and easy to service.
Mh I don't know. Guess it depends on the game then. I play most games with the touch pads. Just so much better if configured right. The touch pads can also be used for abilities or menus or inventory slots etc. It gives the steam deck so much versatility. You can play everything from a joystick only game To mouse dependent games to shooter.
What about like a win mini 4 where you get the keyboard built in then you don't need to sit anything down just thumb type. These seem super cool. I don't understand what a touchpad adds. Other than to mouse scroll. I assume the touchpad is like a laptop.
