People keep saying PSN is slow as fuck, that maybe true a couple of years ago. Now its pretty much ok. What's atrocious is the install times.
psn has always been slow as all hell for me. Like the Op, this is across three different houses, each with multiple, different 'net providers. I'm in Australia, so I don't know if location is part of the problem, but I wont be paying for psn with the ps4 unless I know the speed has massively improved along with general connections to other players.
Ohh and install time? Jesus wept. I turned my 360 on the other night to play something and nearly cried tears of joy at the 4MB update which takes seconds to dl/install. I hope Sony don't get too carried away with how powerful their console is and put a hell of a lot more work into the OS/backend stuff.
