I curse every time I accidentally click iTunes or Photos, as it means I have to wait minutes for my computer to stop lagging before I can close it. Worse, if you exceed physical memory, it seems to have a permanent slowdown until you restart. That's a feature back from the Win XP days. The latest updates to iOS seem to make things laggier as well, to the point where the keyboard might pause after I hit a key.
