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?)
I play a mixture of both games I’ve bought and games through Game Pass. Xbox cloud gaming isn’t great and I think it works for certain games but latency is a no go for me. One reason I like keeping Game Pass is that I often like to trial games before committing and for only $10/mo, it allows me to do this. Before the service exsited, I can easily waste $30+ buying games that I later learn I don’t really enjoy.
