I am new to the physics forums and this is my first post and it is sorta scary but hey. I am looking at an emachines computer to buy. I like the look of it, it is well priced and seems to have possibilities to upgrade in the future. The one hangup is that i read on an online review that you have to use the keyboard and mouse that came with it. I was wondering if there is any way around this and why this might be. (any input on a brand/ model of computer would be helpful.) here is a link it may be of some use to people who know what they are talking about.
