I actually have three also, a desktop, a laptop and a netbook. I use my desktop for gaming, online streaming and such, that requires higher system info's, because it's easier to upgrade in desktop and a lot cheaper compared to laptops. I usually use my laptop for writing documents, also for surfing, when I needed things for my work such as resume's. Then my netbook for my presentation in schools and work. Seems they have different use huh? But frankly, all of these can be done in just one unit, problem is these units, such as high-graded laptops are really expensive for me. So I'll be sticking with these that I have. Hopefully in future I can have one that will suffice everything that I need.
