I've been told to stop the Mac worshiping, and I will try, but I just had to post the following...
I had the misfortune of having to work on one of our PCs for a day. Many aspects of it were painful, but the worst was using Internet Explorer to surf the web. The web on a PC is a very scary place. It's not just the sheer frustration of the never-ending torrent of pop-ups, the web on a PC feels like you're walking through Manhattan Island in the film "Escape from New York". It's a dark, scary and dangerous place ruled by criminals. Folks, it's not like that on a Mac, it just isn't, and it shouldn't have to be that way on a PC either.
Anyway, the new US "Get a Mac" advert illustrated it perfectly for me.
