I have not seen any previous posts, but I do not think you should bash the guy for his comment. Aperture IS slow and buggy. I am a huge Apple fan and have been for years before the entire Intel thing, however Aperture seems to always be the most unstable thing on my computer, making my computer run hot, draining my batteries, crashing my computer, and worst of all freezing up this brand new Macbook Pro so nothing else works either and forcing me into a manual shut down by holding the power button. Apple really has a lot of work to do on the stability issues. At least it runs MUCH BETTER than it did when Aperture 3.0 was first released. Let me tell you, I was super close to saying screw it and purchasing Lightroom.
