Hi I've just finished college and am going to university soon, i've got a dell inspiron 1545 at the moment but am looking into buying a mac. I will be mainly word processing, web browsing, downloading torrents (which is the best torrent client for mac and are viruses an issue?). However i still want a fast laptop and i'm interested in using photoshop (can this be downloaded free from anywhere?). Therefore i was looking into getting the new unibody macbook, however on amazon it's £802, and the pro is £882 - just £80 difference. Is it worth getting a macbook pro? Also as far as torrents are concerned - is there an app which scans them individually for viruses before download (if viruses are an issue). Thanks!
