Hi all...I've been lurking here for awhile, posted a few times. I am currently saving up for a rMBP. I'm done with Windows and despise my HP computer (that I'm on when I post here). Sometimes when I am typing on my HP, if I move my hand across the trackpad, it messes up my page that I'm on. Sometimes to the degree of closing it (without me pressing any buttons). It's random and not all the time but enough that it's annoying. My ? is, does this ever happen while typing on a rMBP? I've not ever used one long enough to "test" that out. Also, does anyone use a mouse with their Macbook? That will take time to get used to if I choose not to use one. Most ppl I know with one do NOT use a mouse....any specific reason for that?
