But Xbox play anywhere titles are not playable in surface, weird
I'm not using the Surface for much gaming related other than CRPGs on other services - my response is purely to his contention that Surface as a product is a lost cause - which I hugely doubt all things considered. For me it is primarily audio workstation, research journals and other work related stuff that often needs a lot of processing power - productivity I guess, but with the benefit of being pretty competent for processing power I need.
Gaming wise, lots of smaller things will work perfectly and some RTS / CRPGs but it's not a priority. Xbox games / play anywhere stuff so far is not going to happen since they are more intensive. Streaming is no issue. I've used Steam's in-home streaming for gaming or other services and stuff locally on my other PC when I got a bit lazy and its flawless, so I'm sure xbox streaming will be fine too, but it hardly has the same usefulness as a native game since the device isn't nearly used much at home vs travelling and working
