This has to be the best thing to happen to Apple since the iPod.
I can see this little baby selling quite well.
Obviously not enough to compete against the market as a whole (or at least yet), but it is a long strain up hill. But this certainly is beneficial to the Macintosh platform as a whole I think.
I for one am looking forward to its release, and I'm playing with the idea of getting one as a second-Mac, as I'm sure the millions of other Mac fans around the world are too. I agree with Wayne about it putting a nail in the Amiga's coffin, however it may encourage Amiga hardware manufacturers to start rethinking their strategies and make stricter price targets. If that is the price of hope for a more diverse computer industry then it is ok with me for I am sick of it being nearly 100% x86/Windows.
Heck, even if the Mac had 95% market share I would still like some level of serious competition (as it stands market share/popularity of other OS's against MS is laughable at best.. at least in the HOME market.)
