PC and MAC difference?

The main "visual" difference between Mac and PC is that you'll find a bitten apple logo on most of the parts of the system, showing it's made by Apple, Inc. Whereas on PCs, you may find logoes of different comapnies like Vaio (by Sony), Dell, HP, Lenovo, Asus, Acer, etc. PCs also have a "Windows" logo in most of the cases. Another common observation is that Macs come only in silver-white colours, whereas PCs in numerous (including silver-white). The Mouse (for Mac desktops) is wireless having no ons (entire surface is multi-touch) whereas for PCs, there's no multitouch on less mouse yet. Mac Laptops have a on less scrollpad, again multitouch. Macs have a "iSight" camera, which is often visible only if seen closely. That's it...but the bitten apple logo is the sure shot way to confirm it's a mac.
