I tried Pandora One last year. I played it in the horrible PS3 browser and sometimes it would freeze up but I ended up canceling Pandora One during my year because all I heard was the same tracks over again and they played too many live tracks especially from Phil Collins. I hate live tracks more than anything. I since switched to Slacker/AOL Radio where I don't hear as many of the same tracks and there are way less live tracks.
You are better with a iPod Touch anyway as eBay has deals on them. You can load the Pandora app or what I use the Slacker and AOL Radio app and you can connect it to your stereo with a dock. It will sound much better then playing it though the cruddy PS3 browser if it has not already froze your PS3 again.
