Jesselp - you're doing a lot better than the majority, I'm sure. I'd say Russ has some very good suggestions.
If you don't want to order online, you probably pass street vendors or electronics stores with even cheaper and/or smaller radio versions - something with earbuds so you can listen on the move. I was very glad to have one in the '03 blackout - news reports on WNYC (1010 WINS was knocked out by the power outage) started explaining the scope of the outages, so I could convince some people still waiting on the subway platform that there wasn't going to be a "next" train that day.
Also, you might want to consider a small Nalgene, like a .5-liter, with water on you. Something you won't break, something you can refill as you walk (unlike the "juice box). The blackout was also a hot day, and it was a long walk home for me (and I was already in Brooklyn...adding Manhattan to the walk would not have been fun).
