Any thoughts on Ubuntu?
I've tested it and like it, but if you're computer challenged you'll want someone good to install it. It needs it's own hard drive partition, which is a different type of partition than Windows uses (Fat 32 or NTFS). And much of your software (Windows based) won't work without additional software that will allow it to run as a shell over Ubuntu. For the person who's looking for simple computing, it's not something I'd recommend...
I'm here if you need help on Opera. I may not be able to handle some inquiries but I can cover the basics... I'll be back in the early afternoon. Golf awaits...
