I just installed Leapord and can already tell it's another great product from Apple. I am so impressed with the ease of installation, although it did take about an hour to install, but considering I only had to hit one button and then walk away and let the program do the rest it was a breeze. The graphics on it are great and the best feature of Leapord is the time machine. This program backs up your computer every hour on the hours and if any of you are like me I have a trigger finger and have deleted things I didn't mean to. With Time Machine I am one click away from retreiving my file and not only from an hour ago but I can go weeks back and find the file I deleted all in about 3 seconds. This program also allows me to track my downloads right on the tool bar so I don't have to go digging through my hard drive to find it!!! Awesome program which makes computer use fun and easy!!
