E-Readers, Travelling, and a Plea for Nook Advice

I'm going to Italy in the fall. 10 days of winey (not whiny) foreign goodness. We're planning on jumping around a lot, renting a car and driving through Tuscany, and a train ride (or two!). Still working on the itinerary. BUT. This poses a colossal problem. Because I do not travel with less than one book per day. No that's not a typo. One book per day of travel.* So that means 10 books.

You see the problem? That's a whole suitcase. And so I have decided to purchase an e-reader. I already have a Sony Pocket Reader, but this will not do because a) I do not like it and b) I want a new gadget and c) I cannot underline or highlight or take notes on books in it and d) it is a few years old already (shocking, I know) and the battery life is leaving something to be desired.

Couple this with the fact that I have a $100 gift card to B&N, and I am leaning towards a Nook. BUT (Always the "but"). Which one? The Nook Color? Or the new e-ink Nook? The latter is definitely a more attractive price... but the former has apps! And email! And color! BUT (there it is again) maybe that is not such a good thing, all that distraction?

Alternatively, I could just buy $100 worth of really long, lightweight paperbacks.

Help, please?

*This method of counting the number of books needed for a trip is tried and true. I took 7 books with me on my 8-day honeymoon and had to purchase a paperback in the Mexican airport. I took 5 books with me on my 5-day trip to Cape Cod and read 3 of them, and I ended up working remotely for a solid day of that 5-day trip.
