First of all, I have no intention to try and pirate, or get windows for free or anything like this, but I also don't want to go out and spend $200 just right now for windows, after just picking up a new 21.5" imac this week. I searched for some type of trial, and found one for Win7 enterprise edition to try for 90 days. The catch is that you are 'supposed' to be in the IT field for this, but I have read that it works just like the other versions out there. Also, after 90 days it will stop working, and you will have to completely uninstall it before getting the full version of windows 7. Is this ok to do with bootcamp? If I understand right, I would insert a blank dvd, and copy the file that is downloaded, and install as I would normally with bootcamp. Is it easy then to simply uninstall this version of windows and the partition, and then install a new version on Win7 after the 90 days? As I said, I have every intention of purchasing the full retail version, but I was lucky to have the wife's blessing in purchasing the new imac; It would be nice to have that timeframe to pick up the retail copy, and be able to see how well Windows works on the new machine. (I am dying to try out The Witcher 2, after I realized I couldn't run it on our original Vista pc). Thanks for any info, it is appreciated.
