Wireless is just temporary, if you have wireless headphones, you have to plug in a wire to charge them. If your computer has a battery built in, you have to plug it in every day to charge. So it's just an extra chore that makes your life worse. Not that exciting.
Maybe everyone fantasizes about being a digital nomad. I do not. I have a great desk, chair, keyboard, and 3 monitors. I couldn't work without them. If I want to see the world, I'll go do that without bringing my computer. A vacation with your computer is just work.
A question I'm asked is "what if there's a power outage" but we have had about 10 total minutes of power outage here in Brooklyn in the 10 years I've lived here (during Hurricane Sandy). My thought is I just won't do any work if there isn't any power. We waste an hour a day dealing with wireless not working, 10 minutes every 10 years is no big deal. ("But what if it's the big one!?" Then my ISP's backup batteries will also be drained and I still can't work.)
