That is literally FOMO.

You are “missing out” on nothing and technology gets better every couple months at this rate. I don’t want to put myself at the mercy of ASUS for support, but their handheld is REALLY nice. Similarly, Aya and GPD have been doing this for the better part of a decade and are largely what the Steam Deck was based on. And GPD in particular have some very interesting form factors

Most of the devices out there are geared toward Windows (which plays with Gamepass). But there are increasing third party efforts to make linux distros and Valve seem to want to push for SteamOS as a distro (and I think Aya have said they want to use it?).

At the end of the day: if the price is right and you think you’ll use it, get it. If not? Fuck it.
