I love mine so much that I didn’t bother replacing my old laptop after it died, I just bought a dock, pulled an old Bluetooth mouse and keyboard out of storage, and the Deck is my daily driver now.
I have fantastic experiences playing mine. I recently upgraded to the OLED and gave the old LCD to a friend, and now he’s addicted to PC gaming as well. We play stuff every weekend, opening Steam voice calls is built right into the UI and it’s a fantastic experience. If you are thinking about getting into gaming, or gifting one to a gamer, I can’t recommend it enough.
At those price points, it would make no sense to get the 64… get the 512. Unless you already have alternate storage sitting around ready to install.
If you got the 64 with a 512 micro SD card, you’d be in for about the same money, give or take no more than $10. You may as well have the faster SSD instead.
