I was an immediate early adopter of the LCD deck, since I’d been waiting for a device like this for years. While I absolutely loved it, I can concede it still felt a bit half-baked, especially on battery life. The OLED version feels like the proper 1.0 of the device in this form factor. Games that would drain the batter of my OG 512 model now run (EDIT) up to 3-4 times as long.
I still carry my portable battery with me for it, but now outside of very long trips (international flights, etc) I don’t need to break it out if I start from a full charge. Plus the screen and user experience on the OLED just looks and feels better. While the OLED Deck isn’t perfect, I’ve been able to happily game so much more than before, and feel confident further iterations on the tech will improve it
