Hello I am new to Mac and I am about to take the plunge. I will wait until June 11th or so for any big announcements but then I will be putting in my order. Here is what I will be using on my computer: Photoshop CS3 (academic version if that makes any difference) Adobe Lightroom Internet (I like several windows open at a time) Word processing I am currently debating between a Macbook and a 20" iMac, barring any major updates. I really love the idea of having a portable laptop but in all honesty it will only leave the house about 2 weeks a year. I do have a nice 19" LCD monitor I can hook up to the laptop though. Also I am planning on upgrading ram on my own and buying an external harddrive (are these easy to use?). So I need something to let me use CS3, Lightroom, and Internet all at the same time. If I don't have MS Office, can I still read MS word/works attachments that are sent by email (I am guessing no but I can hope)?
