I think it is a neat feature I have Pandora show up on the screen along with Internet radio. I may forgoe the Sirius when the trial expires. I also like the fact that there is yelp and more apps coming along.
Facebook and Twitter are not selling points for me, but the rest is. it's tough because I went back and forth OB different options and this is one I kept coming back to along with the technology package.
I skipped premium in my 335i to get technology and premium sound.
