It's all about want, Roger -- not need, as there is more than one way to accomplish most anything.
I've worked with computers, professionally, my entire adult life, and have gone from a climate-controlled, room-sized computers to tiny, hand-held devices.
I have a love/love relationship with my electronic and digital tools and have made an informed, deliberate choice to use them whenever, and in any way that works for me. I want to.
On the other hand, I've never had a cell phone. That's something I decided I could live without.
So, I guess it's all about want and personal choice.
The question of value is subjective. Did 'Pet Rocks' have any value? Yes, as long as the market for them was there.
If you're enjoying your digital pointillism, it's already valuable; if you can sell it, that's a different kind of value. Both can be gratifying.
How you get there is your choice. :-)
