As I mentioned in another post, I will be in town this summer. My girlfriend has put me in charge of Internet. (or, more accurately, I suppose, I refuse to use her terrible Internet)
Comcast quoted the gf a good price, but has gone up $15/month from that quoted a price. I told her she should jump on that price while it was available, but it was more than whatever the cheapest from Verizon was and her Internet is fine for her. It is impossible for her to use the Internet and for me to be on a Skype call at the same time. I use Skype (or other communications technology depending on who we are recording with on a particular day) all the time for what is going to be my job for the summer...podcasting.
She currently has Verizon and we could just get a faster tier there potentially. I currently have Comcast and it is fine, but the pricing structure is clearly different in Baltimore (as I am paying more for less), so I can't just say "this is what I want" and get the best price.
Clear sounds interesting, but I'm a little concerned it won't be fast enough for my needs.
I have had problems with Charter and Time Warner in the past, but would be willing to give them another shot with sufficient recommendation.
I have heard good things about AT&T U-Verse, but if I remember correctly it is on the expensive side...or at least it was when I lived in Madison.
