I seriously doubt that ASUS put any focus on making it user serviceable either. I really want a Deck, but I'm waiting for refurbished units to be back in stock because the price difference is just too big to justify a brand new unit.
Does it have a proper suspend/resume function for games? For me, that's pretty much the benchmark for reaching a "Steam Deck-level" experience. But I think none of the other handhelds have it.
Every PC in my house except for my hypervisor has an Asus motherboard. No thanks, I'll continue using what I've used for two decades without issue, thanks.
I've had 3 of their motherboards die, one came without the USB3 header properly attached, and each time they wanted me to pay them for replacements.
I had a phone of theirs, the motherboard died and they wanted $300 for the replacement. It took 8 months for them to send the phone back to me and it was still broken, parts of the phone that were working like RGB and NFC no longer were.
