Attention Apple users. Have you upgraded your Mac to Snow Leopard OSyet? ( I just did last night). I just found out that Apple's new Snow Leopard Operating System actually saves energy over the old OS X Leopard. For example; the 17 inch Apple Macbook Pro using the OS X Leopard 10.5.6 system will consume about 85.09 kWh annually, while Snow Leopard uses 76.74 kWh annually. What's that mean in cost savings? Only about $.95 per year per computer, but there's a whole lotta Mac users out there, so spend the $29 and get the upgrade!
