I wanted to post a comment after reading ... but saw the long list of comments and decided not to.
As many mentioned, a 6.0 Mac vs a 10.x Mac will yield the same results. So it is quite apparent that this is a fan boy out on a MS-bashing trip. Childish at best.
MS, Mac, Palm, HP, Dell, IBM, Sony and any MNCs out there, have done some good and some bad. Go ahead and point out their fault where they mess up but don't turn it into a religious affair to skewer them whenever you get a chance. It's simply insane.
And I think they deserve credit where they are due as well. Let's play fair.
The other point is that the very skewed choice of 'simple' everyday applications is definitely not quite what ppl do today. I no longer code so frequently, but that 6.0 Mac is definitely not gonna let me code and build binaries for Windows, Palm, PocketPC, HandheldPC and linux. Windows does, albeit using cygwin for Palm and linux. I don't just surf text based web sites today. I surf content rich sites like youtube, ajax based sites like gmail and I like using Firefox with like ... 13 ~ 20+ tabs open. Yes, it's wierd, but I do. And I think the 20+% FF users probably can attest to the ease of using tabs, never mind 2 or 20. 6.0 Mac does not run FF right?
I also like to be able to plug in my SD and CF card from my pda, mini-sd from my phone and thumbdrives to share data around. I also like to use Bluetooth to sync up with my phone or use the USB 2.0 cable if I want an easier sync up and no blue-jacking.
Surfing the net wirelessly with 802.11g is also good and so is peer network using wifi for sharing files between two notebooks. Oh did I also mention that I like downloading ubuntu and Redhat iso images at 5000mbps broadband and burning to disc. After that, I like to dual-boot to Ubuntu and someday try installing Redhat just to see how it works.
Try all that with 6.0 Mac or for matter with a 1986 Mac+.
