Outside of the major changes of the screen and battery, there’s minor changes in pretty much every area of the OLED. Whether that’s worth it depends. For me, the Deck was my main device, and for that it was completely worth selling the old model and upgrading. If it won’t be your primary gaming device or it will almost always be docked (so not benefiting from the screen or battery), then maybe not. In either case, the power is basically identical and some software changes have been made to massively improve the LCD screen, so you really can’t go wrong.
Yup. My wife’s car is a '22 and while overall solid drives her crazy with its sensors yelling at her. Thankfully, the auto adjustment to steering if you ‘veer out of your lane’ can be disabled. It still beeps at her for usually no good reason, though. Meanwhile, I hate it because it uses Android auto and is absolutely horrible at managing multiple phones. When I drive it won’t connect. Meanwhile, when she gets home, it hijacks my bluetooth even if I’m listening to something with my headphones. If I unpair it on the phone side it spams pair requests until I block it.
Meanwhile, my car is roughly 10 years old, runs just fine, doesn’t beep just because I used my turn signal with a car next to me, and has basic bluetooth that just works. I much prefer mine.
