Hello,
I'm a first year student at Davis too right now. My experience with the laptops have been largely positive. I was a little iffy about the tablet feature at first because I've never used one, but it's dramatically changed how I take notes and study. Some things I like about it:
1. eliminates paper... saves paper, don't have to buy it, don't have to carry it around, or worry about losing them.
2. organized. i have all my notes organized by class and lecture. it's really easy with Microsoft Onenote or Journal.
3. I like using the tablet like a dry erase board. it's good for working out problems, writing out biochem pathways, etc
4. having all my notes in one place. this is pretty cool. like today in nutrition, the prof was talking about arginine deficiency. we talked about argine in biochem last quarter and all it took was a few clicks for me to bring up the arginine pathway.
how you use the tablet is up to you. you can download the powerpoint lecture slides and highlight important information, write notes on the slide or off to the side, color code things, take notes in microsoft Word, whatever. You can use the keyboard to type notes or use the pen to write. It's really up to you. I know some people still prefer regular paper notes, but I'm a big fan of the tablet.
As of now, I can't think of any special Davis software. They might have some in the future, but I can't see why it wouldn't run on any other computer. A reason they want everyone to have the same laptop is so that everyone is on the same page. no one is left behind, everyone would have internet access, everyone could play the videos, etc.
we did get a free trial of digital textbooks, which was pretty cool. It was easy to find information by searching and you didn't have to lug them around. i've yet to purchase any digital textbooks though. for now, i'm sticking with paper textbooks.
I'm not sure if that answered you question, but feel free to keep the questions coming...
Oh, just wondering, do know you Dr. Parker over at Berkeley?
