First Class in a Direct ICE from Copenhagen, DK to Berlin, DE

I delayed buying my connecting ticket from Copenhagen, DK to Berlin, DE, so the only tickets left were First Class on a direct ICE. The next second class ticket would leave 5 hours later and arrive 10 hours later. I decided to spring the extra 50€ for first class to Berlin. I mean, why not?

First class is not worth the extra price obviously unless you are in a hurry or have a laptop. Oh wait, I have a laptop, I plugged in and had a fun 7 hour trip coding many fun projects.
