Here's the short list
It boots in 11 seconds
I can push the power buttom off any time with out trashing software
I can cruise the internet with being bombed with spam, spyware, popups, virus'.......
It can do all the basics any pc can, mail, word processing, graphics....
And though it's not perfect, over the years it has been much more crash proof than windows.
New hardware is kind of expensive, but used stuff is available and cheaper.
And we're just waiting untill we get our "new amiga"
(AmigaOne ,UEA Pegasos....)
