Just bought myself a new MBP (with 8gb ram) as an upgrade from my 4 year old Macbook. My iPhoto library is growing slowly but steadily (a few thousand pictures at present), and I've been considering Aperture 3. I like the idea of more manual control over the organisation of the photos, plus the additional editing features. However, reading various reviews on the Mac App store and elsewhere, I'm concerned about the number of people reporting regular crashes, memory leaks and so on. I know people with a complaint tend to be far more vocal than those who are happy, so it's entirely possible that it's a small but noisy minority having trouble, while most people are bug-free. Just wondered what people's experiences were, whether it may be worth waiting for Aperture 4, or indeed just sticking with iPhoto? For the price, if Aperture 3 was stable, I'd have it tomorrow, but few things annoy me more than buggy software. Anybody out there care to comment on their experiences, good or bad? Cheers!
