Valve announces Steam Deck OLED, an updated version of its portable gaming PC that will arrive one week from today on November 16th. The big change is obvious from the title, as this replaces the original LED with a slightly larger OLED screen, and it also includes more storage, a bigger battery, and more. Thus it promises high dynamic range, longer battery life, and faster downloads. As noted here, this raises the base price to USD$549.00. This page shows that the price on the updated base 256 GB LED model has dropped to $399.00 and there's also a 1TB OLED model that's $649.00. There's also clearance pricing on the original 64GB and 512GB units while supplies last. Here's more:

Brighter colors, blacker blacks
Steam Deck’s HDR OLED display is designed from the ground up for gaming, with striking contrast, brilliant clarity, and a larger picture. With more colors, pure blacks, and amazing motion rendition, you’ll see your games in a new light.

More time to play
Steam Deck OLED has 30-50% more battery life. We fit a bigger battery into the case, and the OLED display draws less power. Add in an updated, more efficient AMD APU and you have way more time to play your favorites.

Faster downloads
Steam Deck OLED comes with Wifi 6E, offering increased bandwidth and lower latency. This means faster downloads (up to 3 times faster!) and stable online play.

Lighter, cooler
Thanks to a bigger fan and updated thermals, Steam Deck OLED runs cooler. It weighs 30g, or ~5% lighter than the LCD model, due to the screen.
