Hi! I am new to the Mac world, I have always owned PCs. I am in my final year of high school and need something to last throughout my undergrad (I realize this may be pushing the life of an up-to-date laptop a bit?). I have decided now that I am buying for myself that a Mac is the best way to go. I am going into the Arts, I use video and photo editing software recreationally (this may change to be more than recreational), I surf the web, I do a lot of data sharing. I travel a lot, and am leaving in a couple months to travel through Europe for a semester abroad, so it would be convenient for the laptop to be lightweight but also long-lasting in terms of software and [other things that I won't pretend I know about]. What kind of laptop do you recommend?
