Wow, I can't believe I read all 36 pages.
I, too, have concerns about the long term outlook for the Mac OS. But, all things considered, this is a great move.
First, a question. How many of you here prefer Windows to the Mac OS? (a rhethoric question) Probably 1% or less. This being the case, why would you ever use Windows except when you needed to? (Business, a special program, etc.) So why would the Mac OS marketshare be threatened? Mac users love the Mac OS, and always will.
Second, what do 90% of computer users use their computers for? (another rhetorical question) Surfing the net, right? Well, think of all those new Mac users who will now boot up their new Intel Macs and begin surfing using Safari. They won't miss IE in the least because the sites they visit to retrieve their web-based e-mail, like Yahoo, will still work just fine. But now these sames users will have a Mac OS version of iTunes to use, along with GarageBand, etc. All good, right?
My big concern remains with programs like Photoshop and GoLive (or whatever). If Adobe won't make these for the Mac OS in the future Mac users will have to be constantly rebooting their computers to move back and forth. But . . . I had this concern before today's announcement.
For me, the upside is that occasionally I need a little program, often free, that can re-encode a video file or do some other small but important task. Today, when I google to find the app I have to see if it comes in a Mac version. In the future I can simply grab the first one I find and install it.
