In my opinion, cell phones are a marketing gimmick. If you need a cell phone to help you arrange a meetup with your friends, you need to learn how to "arrange" a meetup.
Yeah, I was able to meet my friends at predetermined places back in the landline years. I don't need a cell phone to set up plans.
But I sure as hell enjoy the freedom a cell phone provides in being able to make changes to plans on the fly-- say switch bars since the first is playing terrible music, or move the BBQ spot a kilometer down the river where it's less crowded.
And yeah, I skied powder before fat powder skis; nobody is going to argue that powder skiing didn't exit before fat pow skis. But I sure as hell enjoy the freedom of skiing different terrain, of being able to make more dramatic last-minute changes to trajectory, and being able to make a broader range of movements on fat powder skis.
