So is anyone else here excited about the Prius Plug-in Hybrid coming out sometime next year?

Couple of questions:

1. Will you have to have some special equipment to install at your house to be able to plug-in?

2. I've heard you will be able to get around 12- 15 miles on just electricity, if you can plug in every 15 miles.. you would simply NOT use any gas.. right?

3. Anyone know how much of a savings it will be in cost in electricity vs. Gas use?

Thanks in advance!
