With Apple computers being my primary computer I have become spoiled with operating system updates and upgrades.  My computer is mine; it is setup just the way I want it.  This is a long process to get it just the way I want it.  The ease of updating was one of the reasons I made the switch to MAC.  When OS 10.6 was released it was the first OS since system 7 that does not support the PowerPC.  Many have commented how this was such a bad thing.  System 7 was released May of 1991, not 2007 which is when Vista was released. 

While I have not installed Windows 7, I have read many of the reviews  about this redesigned operating system.  Review after review states there is no straight through upgrade for XP.  Please read this carefully because it means you will have to spend a lot of time readjusting all of your settings, and be out more than $100.  

Compatibility issues were identified through several sites available to MAC users to check to see if their software was compatible with the new OS 10.6, I have only found the Windows site for checking compatibilities.  They lost my trust with Vista and have not shown me enough to switch back.
