I'm actually planning on getting either one of these or a Titanium G4. I've worked with Macs before, and I haven't really had any problems that could be attributed to the OS--and I've actually upgraded a 7200 to a G4. <IMG SRC="smilies/biggrin.gif" border="0">
My main reason for getting a Mac is that it's probably either that or suffer with XP, and getting XP is in my "not on your Nimda-infected, product-activated, Office-Assistant-Assisted life." It's supposed to be their most secure OS yet, but there have been reports of gaping holes, and as for Product Activation...
Well, suffice it to say that I do not trust any company that makes it so obvious that they think all their customers are thieves. Maybe if they were willing to take full responsibility for any and all downtime or damage caused by the design flaws in their OS, I'd be more forgiving of them, but for them to demand this much and offer so little, it doesn't work for me.
Windows is the Baywatch of operating systems (anybody who knows what world record is often associated with that show knows what I'm talking about).
Plus, MS makes many fine products for the Mac, and they're actually motivated to make the products better instead of adding in extraneous features because they think some out-of-the-blue product is going to attempt to horn in on their racket.
