No discrete mouse buttons == FAIL
As Einstein purportedly said, "Make everything as simple as possible, but not simpler." This goes for the integrated mouse/trackpad layout that a lot of netbook/laptop computers are sporting lately. I have never found one that I like. The layout on the Dell Mini, for example, is horrible. Cutting and pasting with one hand is just about impossible. When are the designers going to learn, a PC is not a mac? Sure, it looks pretty, but try to use it in Windows or Linux.
