I don’t know that it is. BigscreenVR is not an Apple product, so your comment doesn’t feel particularly relevant.
They probably chose iPhones because they’re the most common device that has the capacity to get a 3D scan of someone’s face. They’re probably able to get semi-consistent results with this approach, whereas opening things up to the wide variety of IR devices in laptops and Android phones would increase the number of variables and make OP’s frustrating experience even more common.
The OEM Steam Deck LCD screen is $65.
The OEM Steam Deck OLED Screen is $95, $145 for the version with the anti-glare etching.
$140 is totally reasonable for an aftermarket product like this.
It might not make sense for most to purchase and install as an upgrade on its own, but it’s the same workflow as a shell swap so the two upgrades can easily go hand in hand. For users with a broken screen, it also provides a repair option that is also an improvement.
Also, just want to point out that flashing a BIOS is a pretty trivial task, strikes me as a bit weird to list the mildest of inconveniences as a deterrent.
I don’t get the impression this is being presented to anyone as “a massive benefit over just buying an OLED model”, but it does cost ~$400 less and reduce waste.
