Technology keeps moving on and after assuring myself that my key apps would work, I bit the bullet and upgraded. As always with an Apple Mac and OS X, the upgrade was easy and trouble free.
When I upgraded to Lion, I installed that on a second hard drive and tested all my apps first, I also waited for the first update from 10.7.0 to 10.7.1 before risking it.
But as Snow Leopard was to Leopard; more of a under the hood polish, then so is Mountain Lion.
Nothing too much to say about it yet, it all works and the computer is definitely a little quicker. The major thing I have noticed is Safari, it really is much faster.
