Thanks to all for the feedback.
I'm still on the fence about switching. I went ahead & ordered a high def DVR box from Comcast, which is coming Wed afternoon. It adds $12 /month to my existing package. This allows me to check out my new toy right away.

I imagine I will make the switch to FIOS before long. My AP/AR clerk has a FIOS install scheduled for this week at her home, I'm anxiously awaiting to hear what she has to say about it.
From what little reading I've done so far, it sounds like a fairly time consuming install, so I'll probably wait till early September, when I'm off 2 weeks, to schedule installation.
