I have a lot to say about using netbooks vs desktop and even laptop computers, but i wanted to start by copying this note i put in the How Many Watts are you Using thread:
FYI, for people using desktop computers, there is a significant difference between those machines and a laptop. Here are one person's notes using a killawatt reader:
desktop and laptop watts
Also, what you do in turn influences watt draw. Internet surfing is pretty low wattage.
Peripherals add to watts, but are usually very efficient if they are USB powered, like a mouse.
Netbooks use even less than laptops.
The author of that link writes: "I averaged 10 to 11 watts with wifi and camera enabled, bluetooth disabled, and screen brightness at 2/5ths...That was a big reason for moving to netbooks...to conserve electricity. There�s no reason to be burning 240-280 watts just surfing the internet for a few hours."
Just food for thought! I have a netbook and love it. I certainly don't miss a desktop or even a laptop. I plug in a mouse and an external monitor and happily surf away. Of course, this won't work for everyone, but for a lot of people, it's plenty. And I am on the computer a lOT.
Netbooks cost very little brand new and do simple computing tasks well. There is no DVD drive, but an external one solves that issue in an inexpensive way, if necessary.
What do you use? Desktop, laptop, netbook, tablet? Are you happy with what you have?
