An apology ...
... for scaring away any potential switchers to the Mini, and for insulting any current/waiting Mini owners! I found out that the "Fast Dial-Up" program provided by my ISP (Telus) was an incredible processor speed and memory hog (it also liked to automatically and annoyingly change Safari settings that I had specified to only be changed manually). Once I deleted it I noticed an incredible boost in overall performance. To really test this out, I decided to open EVERY program in my dock (inc. all iLife applications and Word, Excel, and PowerPoint) and upon doing this I still had about 256MB free! And there was very little lag when working in one of those programs with all others still open.
So yes, I realize only now that the Mini IS a rather excellent machine when maxed-out with 1GB RAM, and so with embarrassment I take back the rants of my previous post.
As for you potential switchers, I'm growing to really like my Mini (my first Mac, BTW), and any problems I've encountered have NOTHING to do with the Mac or the provided software, but rather with the odd third-party program that doesn't like to install properly. But I eventually find ways around these issues too thanks to the many Mac-wise minds here on this forum.
So again, thanks to fellow forum members and I apologize again for getting so carried away.
