While Snow Leopard does have some beautiful icons, it appears that Snow Leopard continues to use this image as an icon to illustrate your other computers.
When browsing a network, this is the icon for a Windows PC — an old, beige CRT monitor with the Blue Screen of Death. In short a crashed Windows computer! Smug & Arrogant ?
I for one am rather amused and embarrassed to see that a company like Apple still has to do it.
