In terms of its overall appearance, not much has changed on the outside of the Legion Go 2. It has the same general shape and detachable controllers as the preview model, alongside an 8.8-inch OLED with a variable 144Hz refresh rate and VESA HDR TrueBlack 1000 certification. Lenovo has kept the ability to use the right controller as a vertical mouse (aka FPS mode) when paired with the handheld's included puck/stand.
The Galaxy Tab S8 Ultra had a dual front-facing camera - as did the Tab S9 Ultra and Tab S10 Ultra. That's cool and all, but the wide notch they caused was not ideal. The upcoming Samsung Galaxy Tab S11 Ultra will go halfway towards fixing the issue - it will only have a single camera on the front. Due to thin bezels, that camera will still live on a notch, but it will be less obtrusive as you can see in the images below.
