Well over 100 hours so far, which is a lot for me personally.
I use to to play Steam games, emulate GBA games, play non-steam games, watch TV, Movies, and YouTube.
I used it as my computer recently at an old school LAN party.
I play card games, turn based strategy games, RTS games, FPS games, arcade games, couch co-op games. It's awesome to play on, it's awesome to mod, it's awesome to use as a portable device, as a home console, or as a portable PC.
I use it with friends on Discord, I listen to podcasts and music while playing by myself. I've used it traveling locally and across the country. I'm gunna use it tomorrow on my TV to watch a live sporting event.
There just hasn't been any real significant complaints I've had at all. It does everything I can think of and more. It's one of the best purchases I've made in years.
