As for the laptop, I've got a Samsung Chromebook (the small, ARM one) running Ubuntu and I recommend it. It's ARM, which makes getting things running a bit hard, and it's not the beefiest, so if you want to wait for the new ones this year that will likely be x86 and beefier for $250, you can do that too. I don't take it on the bus though. That was the first bit of advice I got from someone else on the bus.
On the flip side, I like to make sure I can get by without a car. Of course, my understanding is that's a whole ton easier up here (Bay Area) than down there.
Congrats on the impending nuptials!
So I stopped reading and started cycling. Much better use of my time, and I was forced to spend that time with my thoughts (and watching my safety on the road) I was better off mentally than when I was kidding myself that I was being productive.
I'm not saying you can't read or work on a commute, but it did not work for me in the slightest.
