Going to buy a (15" macbook pro). This is what I do on my computer: read and write e-mails, surf the internet extensively, watch videos, use itunes, and type documents, scan and store lots of documents). Use many applications simultaneously (i.e., internet, ical, email, web browser, maybe quicktime, etc.). In the past I've had a macbook which was nice, but it's a couple of years old and the webbrowser feels a little slow, videos don't work as well, etc. So I'm thinking of getting a macbook pro this time. I'm thinking of getting the lowest level of macbook pro (15"), but I'm wondering if it will have enough power for me, given that I sometimes am running multiple things at once and thus maybe I need more memory or something. The guy at the macstore says even the macbook pro is overkill for me, but I thought I would check in with you guys.
