I wasn't big into portable gaming though I have owned every portable Nintendo has made except for the DS until the Switch made me a believer. My 2DS XL covered me for months during the power outage from Hurricane Maria in Puerto Rico. Once the power came back on in February I found myself playing PS4 as usual but with limited time since my toddler uses the TV to watch his cartoons. I got a Switch in mid February mainly for BotW. I have to say that after playing the game for more than 105 hours, I have played about 90 of those hours in portable mode. The game looks fantastic on the big screen but I have found that the smaller screen is nearly as good with the added play anywhere convinience. Power regularly goes out here so it has been a fine investment and my gaming time has increased.
Damn, I guess I was one of the few "lucky" ones. I was without power for only 18 days after the hurricane. I don't think a NS would've work with me in this situation. I didn't have an electric generator (I live in a condo), so the NS would've only work for a couple of hours.
