I agree, don't bother with Mini - the full suit works fine on anything from
the last 5-8 years easily. One of the machines I use it on is a 1.4Ghz Core 2
Duo very easily.
If there are any issues you have just ask as, there is always some here to
help out. If you need recommendations for alternaives to proprietory software
there is almost always guranteed to an excellent solution.
The best advice is simply to give it a try, you will be surprised at just how
easy and how powerful these free systems can be.
