I’m not sure I would.
I did get my first PC for a small business. It was pretty useful for that but now I find that most of my PC time is when I’m connected to the net. If there were no internet I may just buy some sort of game machine and play games that way.
Maybe you use a computer to create art of some sort, but if your art is in most part, published on the internet, then maybe you wouldn’t be creating that art.
I do have a PC at work and if I needed to print some mailing lables or such I could do it there. I would really miss online banking and Quicken is really handy for balancing my bank accounts but then again, online banking makes that really easy.
So if there were no internet, would you own/use a computer?
