John,

Having been a beta tester for system 7, I must admit a little bit of prejudice.

I have been running 7.0 for almost 6 months non stop. It is great!!

When I am not running 7.0 it seems very ungainly. If you can aford to upgrade the memory, I would do it soon. You will have to make some concessions, as to some of your favorite programs, because not all of them will work.
