Don't have Game Pass, but I believe the options on Deck are currently to either install Windows and use the Xbox app, or following these instructions to access Xbox Cloud Gaming from SteamOS. (Assume that's what you meant?)
MS have also been toyed with the idea of making a Game Pass specific environment for Handheld PCs including the Deck, but no concrete announcements afaik.
Do you only plan on playing games available through Game Pass? I know there's a couple of handheld devices (not really handheld PCs, Switch/Deck-esque with Android and smart phone hardware) that are built specifically for Xbox's cloud gaming. (Maybe you don't even know what you intend to play at this stage, and just expect to play whatever's available without paying more money?)
If you buy a Steam Deck you'd probably eventually end up getting a bunch of things through Steam's big sales (you'd have money spare to do so, if nothing else). If you buy a strong laptop, you'd have access to the same sales, and you might want to buy more games anyway to justify the relative price. Hard to really guess what use case would suit you without knowing what future you would want to play (or how well future Game Pass would correlate).
Also, are there any issues still plaguing the device?
The only real issue I ever had was some WiFi connectivity problems, but I haven't experienced those for months now. I genuinely struggle to understand the experience of the other commenter, simply because it's so far from my own experiences. And if anything I've found Steam's use of Deck-Verified to be pretty conservative at times.
As long as I've had the thing there's been a fairly constant stream of updates and bugfixes.
After all, the Steam Deck is still a first gen product. I can’t wait to see what they will do in their next iteration.
Hah, hard to know when that'll appear. I've been waiting years for a second iteration of the index, and at this point I wish I'd just bought one years ago. Valve aren't exactly the most transparent company with their ongoing projects.
Yeah, that's a great use for it. I guess I rely on Steam refunds being automatic under 2 hours played, but it's not quite the same liberty to try things as with Game Pass. Certainly seems like a no-brainer if you have an Xbox (or at least it was even a decision before they decided to make Xbox Live and Game Pass the same thing).
