That's interesting. I would have thought that the Roku would have more apps and that they would be more current. I still feel that in general a media streamer is a better option, but it is nice that you get apps with BD players these days. The one issue is that they stop receiving updates after the first year, for the most part. The PS3 is still one of the few players that will receive app updates, keeping up with other devices. But it is interesting how apps vary on some players. I noticed PQ differences on my PS3 vs 2013 Panasonic TV vs 2013 Panasonic BD player. And sometimes the TV's apps, particularly Hulu, will stutter while the BD player and PS3 are rock-solid. All devices are wired. The TV and BD player UIs are the same, but I don't know if the apps are the same version. Sometimes the apps may appear the same but they differ. Anyway, glad the S6200 is working well for you.
One thing I hated about the Sony S5100 was that you had to connect to Sony's network service to get to the apps. And since I didn't use quick start, I had to log in every time I wanted to use the apps, which was annoying.
