There was something I noticed right away after updating to OS X 10.8. My Macbook (Late 2008) has ran smoother and faster than it since I got it almost 4 years ago. Recently, I updated it to 8 GB of RAM, I had the correct Boot ROM in which to do it. I had some improvements at 4 GB with Lion, but didn't notice it much after I put the last 4 in. Since my update to 10.8, my Macbook just seems faster. Safari is blazing quick. iTunes opens in a shorter amount of time. Just all around improvement! Has anyone else had similar improvements with older Intel Macs?
