I don't know where you heard that, but it is incorrect at this time. There have been some rumors that this might come in the future.
There is something called Verizon Call Assistant, which does provide a display of an incoming call on your PC. It also has a website where you can view your incoming calls. There are supposedly enhancements coming for Call Assistant, but we haven't seen anything yet. I have Call Assistnat, it works well for me, but is pretty basic now. And some people have experienced severe memory problems on their PCs when using Call Assistant (I don't have those memory problems, affects some and not others, there is a thread here about the problem).

Apparently Comcast and Direct TV are one step head of Verizon regarding this issue. Guess we will have to wait and see what develops with Verizon service.
