Lenovo Legion Go S with SteamOS will land May 25 for $50 more than expected

Looking at the specs:

Positives:

• Higher refresh rate (with VRR) and slightly larger screen (so smaller bezel), higher resolution.
• Hall effect joysticks
• Possibly better speakers

Negatives:

• IPS instead of OLED display (but a good quality one at least)
• Only one touchpad, and its tiny
• Seems to be only 2 back buttons instead of 4 on the deck

Neutral / unknown:

• Long term support compared to official Valve devices (hopefully Valve is handling this for third party devices similar to Bazzite).
• Price seems to be the similar to the Deck OLED model (depending on region)

Going by the Verge review of the Windows version of the hardware, it seems the SOC of this isn't that powerful (and may even be outperformed by the Deck when rendering at 720p on both systems with some games): https://www.theverge.com/reviews/617613/lenovo-legion-go-s-review-feels-good-plays-bad

They did see framerates improve with Bazzite, so presumably the Steam OS release will have similar improvements.

Real question is if the software/firmware is open source. They have no incentive to maintain a orphan kernel long term. Any hardware without mainline supported kernel modules, and with a 3rd party reputable maintainer for each should be a no-go.

Better ergonomics
