I did the $250 "online" option. Wasn't really pleased with the quality but doing "game mix" was cool (4 games on screen at once). Although, when you do game-mix view, you can't also do fullscreen, so it's 4 tiny screens within a video screen on your browser. Lame. Nice to have an option the PS3 doesn't have.
Didn't try pausing anything, which was a nice option on the PS3 last year. Pause and go about your Sunday activities, come back and fast forward as you like.
Quality-wise? Last year the PS3 app was either inoperable (week 1), horrid (often), acceptable (75% of the time), and sometimes it would actually look good. But the Audio, whoa, at its best was terrible. There were also audio/video sync issues often. This combined with the online-only option being $250 is why I went that route this year.
Here's hoping the online stream looks better next week. It was a blocky, compressed mess this week, but at least it worked. I even watched over tmobile "4G" and despite the quality being even worse, it did function (though not every time). Yet there was a nagging "Play" arrow-symbol on the middle of the screen that would not go away.
