A few words from Tech Support:

"If you hate PCs, get on the Internet and download one of those desktop enhancements that make your computer look just like a Mac, down to the sad faces replacing verbose error messages. We find it refreshing to troubleshoot the nuances in that sad little face instead of some cold forbidding hexadecimal integer."
