Steam Deck OLED review: Includes specs on new screen and other improvements

This is the best coverage of the new Deck that I've seen yet.

Upgraded:

• 7.4" OLED HDR screen with a 90hz refresh rate and 600 nits brightness(with 1000 nits peak brightness), (old screen 7" LCD with 60hz refresh and 400 nits brightness). Touchscreen accuracy and responsiveness is reportedly improved.
• Longer battery life. Improvements to software and hardware are supposed to increase the battery life by 30-50%. New battery is 50wh vs original 40. Original decks will see some of this improvement thanks to software/bios updates, but not as much as the new Decks. The new Deck charges faster as well, charge from 20 to 80% battery in 45 min.
• 6E wifi module for improved wifi speed.
• Dedicated bluetooth module, allowing better audio quality over bluetooth and the option to wake the steam deck from a bluetooth controller. Will also support more controllers at once for multiplayer.
• Faster RAM, 6400 MT/s vs 5500 MT/s on original.
• More repairable. The screws are now torx, and all thread into metal screw holes. Should prevent stripped screws that were the most common issues with SSD replacements.
• New carrying case, for the 1TB model, there's an insert case inside the full size case. The insert can be pulled out and used as a slim carrying case when you don't need full protection.
• Weighs 5% less.

Prices:

$649 - 1TB OLED

$529 - 512GB OLED

$399 - 256GB LCD

For a limited time, Valve will sell a special edition 1TB OLED with a translucent shell for $679, only in the US and Canada. Expected to sell out quickly.

Note: I'm updating this as I get more information, so the written out info will change as I learn more.
