I'll be 100% honest here.
I'm 25 now. I went to college when I was 17 to learn design. Since then I have done the six months or so at college, 2 years as a Mac Operator at a local paper, a year as a Mac Operator at a print firm. Then I went to work for Apple. I did about six months purely on the sale floor, then a year doing around 30 hours a week of training on both the store's Macs and Macs that people brought in. In short, I have 'met' probably 800+ Macs. Then I went to a reseller and have been there since September, so that's another 9 months of sales, training and tech support.
I've seen a Kernel Panic about four times - certainly less than six or seven. It's very rare, and when it happens it's usually because the Mac is very ill indeed.
In my work I was and am chummy with hundreds of customers - consumers and pros. I was also and still am chummy with a fair few Apple technicans. I know the ugly side of macs, I know what's right and what's wrong.
Apple make only one product that I really don't believe in and don't trust, and that's the Time Capsule. They are utter pants and die for fun. Everything else varies from acceptable to awesome, mostly erring towards the awesome. And I've been on all the sides of the fence - consumer, professional user, and Apple employee.
Don't mistake me for a fanboy either - I have some very strong opinions about Apple Retail that I wouldn't dare to divulge in 'public', but I do believe in their products, and I took some convincing. I only started to think they were worth having in the average person's home when Tiger came out, until then I felt they were fantastic for graphics/pre-press/production work but severely lacking for home users.
I do agree however that the Kernel Panic is absolutely the most offensive and aggravating way for a computer to fail. The whole things tops, then a grey background, then the image you've posted slowly stomps down the screen in about ten steps. It makes me rage.
