My grandmother hated her computer when we first built her one. She said accountants would never use computers. That having a pencil and paper in front of her, where she could simply erase and re-write numbers. How could we fix what's not broken? Nowadays if you use a pencil and paper you're an idiot, and even she will recognize that. SO the question is : Who is more stubborn? My grandma or your local hydro store?
The moral of the story is LED's are proven by now. Everyone knows they work, if you still doubt them then you haven't done the proper research. Plasma lighting has an even brighter future than LED's because they can imitate the sun's spectrum. These 2 advances are the future of indoor lighting, there is no question. People are going to have no choice but to switch eventually or grow in the past. I don't think any of us are using a 386 with Windows 3.1 to view this website....And I own an Xbox 360......not a Commodore 64. But the switch was rough....I was very reluctant because I loved my old commodore......lol
