You have the right idea, read like a fiend.
If you just want to read, a kindle is so much better than real books. So much better. There's one exception - graphics in kindle books suck. So if you are counting on looking at technical books, get a tablet so you can zoom in on graphics and see what they actually are.
Most newspapers have a kindle version you can subscribe to that downloads early in the morning. I liked the Washington Post, but I liked the print version better. It's time to end that, though.
Many trains have wireless. I think a tablet would be your best friend if you want to interact. A tablet makes a good-enough reader for 45 minutes, and you can interact.
I have a netbook. It's the worst of all worlds. Bad for reading (wrong screen orientation), bad for browsing (screens too small, and it's in the wrong orientation for mobile sites) and bad for work (screen is too small to do serious stuff like spreadsheets, etc. If you are going this route, get the smallest, lightest laptop with a full-size keyboard you can find. A 10" screen is just not big enough. Get at least a 12" display.
Just my opinions.
