One thing to knock on the xfinity app a little, it requires you to be on xfinity internet to use. I had it a long time at my moms house, but when I moved out, I switched to directv/att internet. My mom continues to use xfinity, and I still use the e-mail and iphone app from when I used to live there. I tried logging into the app here, hoping to get the best of both worlds, but it doesn't work without a working connection to xfinity internet. From what I can tell, about the only thing useful at all about this app is getting ondemand in a bedroom without a cable box, through the xbox. Other than that, what's the point? I see why they did it this way, sorta, but this could've been big for, say, college students, who went into a dorm and can't afford a cable bill to be able to use a portion of their family's cable while away.
