my graduation and eighteenth birthday are next week. and i want a new mac. definatley a macbook pro, but im nervous about the size. Both my mom and my ten year old brother have 12 inch ibooks, and i love the size and portability. I'm going to see if monday brings an ultra portable, but if not, does anyone find the size of the 15 inch a hassle? I'm a graphic designer and plan on majoring in that in college this fall, so i like screen space, but i have an iMac for that. are the macbook pros heavy? hard to get around? thanks everyone.
