Stogi makes some excellent points.
6. And lastly, while gaming systems become more prevelant, dedicated gamers will decline.
This one is right on the money. Technology has a way of becoming popular and destroying hobbies.
- The decline of Hi Fi as a hobby. Twenty Five years ago, everybody who was into music has a big stereo in their living room with big speakers, tuners, receivers, tape, record and disc players. Along came digital music and the ability to play music anywhere. NOTE: music did not go aways, just the classic audiophile.
- The decline of photography as a hobby. Multiple cameras, multiple lenses, dark rooms and film. Now every phone has a camera built in. You don't have to take the perfect shop, you can use Photoshop to make it perfect.
- The decline of PC building as a hobby. I saw this one personally. The computer shop I worked in had a steady stream of customers buying motherboards, drives and more. Enthusiasts would always be building and upgrading their computers. This slowed down to a trickle by the end of the last decade. Most people bought a cheap laptop and supplemented with a smart phone or tablet.
In all these cases, The results that the hobby produced became cheaper, ubiquitous, required less components and effort. All these hobbies still exist, the things that replaced them offer inferior results, but they are good enough.
There are still music, photos, and computing. But fewer people are dedicated to them in the same way.
As for Nintendo's handhelds, I would strive to make it last a week. That would be my goal. Each iteration would last longer and longer till it lasts a week.
I'm not really sure what this means.
The battery could last a week.
