I bought a MacBook in November (2GHz Core 2 Duo). I've owned Macs before, but not since the OS X switch. I've also been using Windows since the original Windows 95 days. Some comments: 1. Apps are significantly slower to load under OS X. On lower spec Windows PCs, Firefox and gvim load in about half a second when nothing is cached yet. Under OS X, Firefox takes ~5 seconds to start. Gvim takes ~3.5 seconds. 2. The dock is maddening. I initially liked it and wondered what all the fuss was about, but now I understand. It takes up valuable real estate, and things I'm working on tend to go behind it. So I turned on auto-hiding for the doc, but I have the same problem. When the cursor hits the edge of the screen, up pops the dock. I tend to use spotlight for launching most apps (Command-Space + part of name + Command-Enter), but the dock is the only way to see what apps are open and to see the trash. The magnification feature is nice, but glitchy when combined with auto-hide: docks pops up in normal size, then jumps to magnified view. What alternatives to the dock are there? 3. A minor nit, but it really bothers me: The Preview window should be centered, not always in the upper left corner. OS X Preview is more flexible, but Windows Image Viewer is more pleasant to use. 4. Great consistency on keyboard shortcuts, at least so far. 5. The Command-3 view for Finder windows is wonderful. That's what I use most of the time, because it's easy to navigate entirely with the keyboard. 6. I still have a problem with accidentally leaving apps running. I used to have the same problem with my old Power Mac. I tend to close the last window of an app, but not close it, so when I unhide the doc I see all these apps runnning. I never have this issue using Windows. 7. CD/DVD burning is clunky. There's no way to say "erase this disc and burn new data to it" in one step? Under raw Windows, this may not be possible either, because every Dell I've used comes with a nice third party program that handles it well. 8. Lest it sound like I'm nit picking too much, the raw capabilities of OS X are wonderful. Getting UNIX utilities out of the box--spectacular.
