Well, being at work (not in a plane or a car), using a decent wifi and good enough internet connection on both sides and not far from home it should be playable in genres that don't require super precise inputs or reactions.
The experience widly depends on the internet connection, and wifi/router quality. Today found a case of a guy I know who did test it here in Spain connecting to a console of his friend who lives 1000KM away. Both using a good fiber internet connection (hundreds of megs on each side), with the console wired, and a decent router properly configured for the wifi where the PS Player was (plus making sure they didn't have any other device connected to internet on these LANs).
In some other cases instead the experience is very bad while trying to play at work in the same city, a couple kilometers away, or even inside their own house when having (I assume due to awful router and configuration, maybe with a lot of interferences or with different devices taking bandwith while remote playing).
And well, always playing in single player games, because online MP via remote play sucks since obviosly the streming requires a lot of bandwith.
The streaming experience is pretty similar to doing remote play on a decent enough (wifi5 or better) phone or table with a DualSense connected. I suggest you to try remote play at work on a phone, tablet or Steamdeck before buying the device, because the streaming quality will be pretty similar.
