re: Poker & Do you play via mobile apps?
I have the PS app (real money) on my iPad
and my Galaxy S7 smartphone. I don't usually play on either for all of the reasons mentioned above, HOWEVER, I played a lot on the iPad after I had knee surgery when sitting at my computer desk wasn't possible. Those apps are quite useful if you have mobility issues, or if you just can't access your computer when you want to play.
Another thing to be aware of - depending on the quality of your wifi, you may find the app hanging quite a bit. I had this problem 2 or 3 years ago. We've since upgraded our router and PS has probably upgraded their app software, so we haven't had the problem in quite a while.
