I know that I want the 27" iMac, but I am not sure which model will meet my needs specifically. Background: I have owned a Macbook, 20" iMac, an iPad, numerous iPods, and currently own a Macbook Pro 13" base model (2009), I am studying Web Application Design and Internet Technology and will be doing some web page design and layout due to that, I do some light video editing through iMovie and do my authoring using iDVD, I listen to a lot of music, I love photography and do some light photo editing, surf the web, compose word, excel, and powerpoint files, etc. Is the base model 27" iMac enough to meet my current and future needs, if all I will ever do is listed above? I think the specs are something along the lines of a dual core processor (clock 3.06 Ghz), 4GB RAM, 1 TB HD, etc. I think that would be sufficient for anything I would ever do. Any thoughts?
