Prob not. I can't compete with the OTs people put out these days
By the way, there is a new 16 minute video of some lads playing around with the OS here:

VERY annoyingly they seem to be stubbornly avoiding trying out multitasking while a game is open/suspended.
FWIW, though, at the start Top Darts seems to be suspended, with a few other apps either open or in a suspended state themselves. But I would still like to actually see someone hopping from game to app etc. to get an idea of speed and how many or which apps can actually be opened without exiting the game.
Anyway, they look around a few different things. An empty PSN store, a near app that seems to have locked up, settings, an empty music player, the content manager (although they obviously couldn't connect to anything), the remote play app (again, couldn't connect to anything), and perhaps more interestingly, the web browser. They check out their own site and youtube. Don't actually try to play a youtube video. The initial page load speed IMO is not great. I hope that's a function of their net connection there rather than that pre-page-load pause you get on some devices :\
Also at the start you can see how hitting the power button while in a game suspends it, Turning it back on brings you to the lock-screen. Going back into the game is very fast.
They also look at the trophies app, which seems to also have activity feed for the player.
