Im living in the dark ages still. Only have an iBook g3 Dual Usb and my XP desktop. Only use the Windows for syncing with iPhone really, not much else, it runs way to slow. Even though my iBook is years old, it runs faster than the desktop and i use my iBook as my main computer. Does everything i want it to do. Word Processing, spreadsheets, Powerpoint, Music, Web Surfing, Emails, Msn and photos.
I really would love a MacBook but couldn't justify spending that much money on something my iBook could do very easily aswell.
