i would NEVER go back to Cablevision. Ive had FIOS since it was offered in my town, and never looked back.
While living at my apartment, we had CV, and it was just bad. Tons of internet issues, we had signal issues with TV quality. and it just sucked.
now im back home with FIOS and wherever i move next will def HAVE to have a FIOS connection, or i will not move there...
and BTW, the MSGHD picture quality is better on FIOS than CV
Pretty much sums up how much better FiOS is than any competitor.. I will also never give up FiOS.. Cable simply cannot compete with fiber optics
