It’s raining gaming handhelds lately. Acer have now announced the New Nitro Blaze 8 and Nitro Blaze 11. Don’t expect SteamOS / Linux on them though, sadly they’re shipping with Windows 11. Never say never though, with Valve expanding SteamOS perhaps we may see Acer jump on board in future too.
A 780M is noticeably better than the Steam Deck GPU, which is what it’ll be compared to.

I suspect that price is a bit high for most people. I think it’s largely coming from those screens.
