Yeah, the only thing I didn't like about it, was that I have to keep it running at all times. I try to run as few apps as possible.
As do I. I'm especially OCD about startup tasks. I see all these people taking screenshots of their task managers on /g/ with 100 processes running and I'm like "WTF?".
However, they really aren't very big resource hogs, especially compared to certain programs that feel the need to use over 300MB of RAM:

Yeah, but I run OS X now, so it's all good. All I run on startup is Dropbox, and InsomniaX (an app that allows macbooks and "Macbooks" alike, to close the lid and not go to sleep. I mean, seriously apple, it's a pretty standard feature for an OS, and it's not hard to implement, get with the program). Other than that, I'm 100% satisfied with OS X, and feel no urge to switch operating systems, like I do when I use Windows or Linux. This may sound like the total opposite of what is usually said, but I feel closed in when I run Windows or Linux, but not so much OS X. Maybe it's because I've used OS X since the developer previews, so I know it inside and out, or maybe I'm just insane, and think different (that one would be quite appropriate, no?)
