I have to agree with Naiya here, the PC (or Windows) in the long run is the best way to go. As was pointed out, many of the iMac's have only i5 CPU's, 4GB RAM & 320GB HDD's. And that was only a recent upgrade. Before that, they shipped with 2GB RAM, very low specs for a $1,200 PC.
One can buy 2 Windows PC's of the same specs for that price, easily. And then there's the software issue. Some things has to be bought from the Apple Store. It may be that way with Windows some day, but I feel that's far away.
Finally, I also realize that Apple has their loyal following. Anyone who stands in line in the rain, snow, cold, whatever for 12+ hours for a phone that can be ordered w/the option of overnight shipping has to be loyal. These customers could afford that extra cash for delivery, but chose to be with the crowd instead. That's not my cup of tea.
I'm a Windows user 1st, Linux 2nd. Windows will make it through this time of change, they have before & will again. Yes, there's a weight on Windows 8, but probably half of that "weight" is the media. Windows 8 will be fine for many users, yes, there are some changes, but I can live with them or find a workaround when needed.
