I have XM because I'm on the family plan with my brother, so it's cheaper than on my own.
I like the music channels due to the fact that they are just that.
We also like the XM radio in the house, since my little Roady2 easily unplugs from car to home, and I also have the 'walkman' kit, so I can have it with me on the beach. The walkman kit was a little bulky, but the price was right.

70's channel plays 70's music and I don't need or want the chatter of a Barry Williams/Greg Brady.
There were a lot of other folks from the 70's I'd much rather listen to if I were to be forced to listen to DJ chatter. And I'm not talking about Danny Bonaduce, another has-been kid-actor from a prime-time TV show.
DJ chatter was fine when records needed to be changed and cued up.

XM has one guy, Sonny Fox, who discreetly does a lot of the announcing on multiple channels. No fanfare of who he is, he just spits out who played what.

Howard just isn't funny anymore and hasn't been for years. So long as I can minimize any exposure to him by keeping to my music channels, I'll keep XM.

With too much chatter, I'll switch back to the Ipod in the car.

I like a lot of the other XM channels, but due to the commericals, I just don't listen to them as much as I would.
Their comedy channels are funny, but they have some really skeevy ads about 40% of the time, mostly about viagra or some weight loss pill, debt reduction, or some other kind of crappy infomercial .
