So this kinda irratates me. I have the 2.2 blacbook, 4gb ram, 320gb hdd. Now when I first bought my macbook, I did not use Illustrator or Photoshop CS3 (for both). Now 1.5 years in, I am using Illustrator and I noticed that when I am working on both (either at the same time, or with one program closed) I sometime get the message in Illustrator "Not enough memory" or "Not enough ram" or when I am saving an image for web and devices "an unknown error has occurred" BUT if I use Illustrator and Photoshop CS3 (for both) on Vista via bootcamp none of these errors occur. I just don't want to imaging what will happen when I use CS4. Is this due to the way Leopard is setup? I am also looking to upgrade...So do you guys think the new macbook or macbook pros would be better? I mean, my current macbook is holding up well...but I just hate these errors. I prefer to work in Leopard than Vista. Hoping to buy both an iMac and Macbook or a Macbook Pro when Snow Leopard comes out.
