Hi John,
Don't mis-interperate what I wrote. The SB will definately play Pandora, and it does it just fine. My only point was that when you are streaming Pandora through the SB, when you go to hit the song skip option, add or bookmark an artist or something similar, Pandora on the SB moves a bit slower than the standard Slimserver interface. I think its due to the internal processing and then communicating to the website.
On the other hand, when you surf into Pandora on your computer, the site runs relatively quick. In turn, if you use your computer to set up and modify your Pandora stations, it is much, much faster. Once you have your stations set up, they read through to the SB seamlessly.
When it comes to Internet radio on the SB, you have thousands and thousands of choices of stations. SB's Slimserver software gives you several hundred to choose from. You can also manually tune into a station that isn't on the Slimserver list (as I understand it).
Bottom line, no worries mate. The SB is a great way to listen to Pandora and Internet radio (not to mention CDs).
