I put a question mark there, because I'm really not sure if it is an upgrade for ourselves. I need to buy 2 new computers: one for myself, one for the designer. I work in web development, which I use nothing more than Word, Terminal, Mail and Safari. So, nothing power hungry at all. However, as you'd suspect, the designer uses Illustrator/Photoshop etc and I'm worried about the decrease in speed, rather than the increase if I buy an Intel iMac for them.
