It's amusing at one point in the past it use to be Apple users and Windows/PC users bashing each other.
Now it's Apple users attacking Apple users. Ironic.
A schism in the cult.

I agree. I never figured out why Apple messed with PPC in the first place. Intel x86 was always faster and far more advanced. I know they were just trying to be different, but different isn't always better. I had a couple of PPC Macs and I guess they were fine, but we were always running slower then the PC's back in the day.
PowerPC was the logical choice for Apple. The Motorola 68000 series was being dropped, and Motorola and IBM were working on the new PowerPC chip as the replacement. PowerPC was big-endian just like 68000, which was more important 'back in the day,' when making those kinds of binary level changes would upset an entire software eco-systems Apple cart. So, Apple went along for the ride. There was real hope that PowerPC was going to throw Intel overboard at the time of introduction. Microsoft at the time was producing Windows NT for MIPS, i386, PowerPC, and Alpha. According to Wiki, versions for SPARC and 'Clipper' were also being developed by a 3rd party, but never sold at retail. OS/2 was also issued in beta-form for PowerPC, including a 'Rosetta' type of software that let x86 apps run.
As it turns out, x86 & Microsoft are two sides of the same coin. Once Microsoft figured this out, all the other versions of NT were cancelled. Alpha lasted one cycle longer than the others.
So, when you add a little history, it doesn't seem so silly that Apple would head to PowerPC instead of Intel. PowerPC was faster than Intel from introduction to about 1996-1997 when the Pentium Pro made a big leap for Intel that carried all the way to the Pentium III. That is what brought Intel back to even, and in the 2003-2004 years, they pulled ahead of IBM PPC 970 on clock speed, until everybody hit the wall. But what Intel did have going for it was low-power laptop chips.
And really, how do you figure that x86, a 30-year-old format with 8 registers, is more advanced than PowerPC, a 15-year old format with 32 registers? The whole advantage to '64-bit' on Intel is actually not to do with 64-bit, but with having 16 registers instead of 8.

Dropping PPC support probably means that Adobe will finally be able to do a total Cocoa rewrite of the remaining Carbon parts of CS, thereby enabling them to offer 64-bit versions across the line. Lightroom was pure Intel and Cocoa from the very beginning, and that's why there's a 64-bit version. Apple's dropped support for 64-bit Carbon, which is why there was a 64-bit version of CS4 on Windows but not Mac OS X.
There is no connection between PPC and Cocoa, or PPC and Carbon. 64-bit Cocoa exists on PowerPC in 10.5 right now. There is only a 64-bit version of Lightroom because it was newer code, written for Cocoa, not because it was for Intel.
