Okay, so my first experience with Lion was a disaster. -Broken Wifi -Very sluggish/laggy performance in Finder -Safari an experience in beach-ball watching -Using Handbrake or other CPU-intensive apps bogged my iMac down so bad I had to restart. These symptoms were the same when I installed over Snow Leopard, and also when I did a clean install. I even went so far as to get a refund from Apple. I'll admit that part was a bit petulant, but I was angry that Apple had released an OS that was so mangled (on my computer). When 10.7.1 came out I was tempted to retry, so I waited a week or so and then did a Time Machine backup of my Snow Leopard setup, in case I was disappointed again. However, I was not disappointed at all with Lion 10.7.1! In fact, my mid-2007 iMac (2GB RAM) has never run better! Everything on the machine runs quicker (and yes, snappier). Safari is running like a dream, and I've ditched Chrome browser for now because Safari is finally every bit as quick. In the spirit of trying out new things, I've started using Launcher instead of going to the Applications section of a Finder window. I can't say Launcher is any better, but it's really no worse. Mission Control is fine with me, too, although not being a power user, I don't use it much. So, since I came on these forums to trash the initially broken version of Lion, I come here to humbly say that the Lion that now runs on my Mac is a definite improvement over Snow Leopard (except for missing Front Row!) I'm now a Lion lover.
