1) It just makes Leopard a DEAD-END for many Mac users without them knowing that when they paid $129 and its still not as stable as TIGER and is still slower than Tiger on PowerPC Macs. It's not like other people haven't posted this. Go to Apple Discussions if you think I'm wrong.
2) Many people purchased Leopard not thinking it was a dead-end or that it would end up buggier than TIGER or that PowerPC support would be discontinued when Apple FIXED Leopard with SNOW LEOPARD which is now BUG-FIXED and OPTIMIZED!
3) G5s are 64bit and could easily run Snow Leopard, but not all of its features, but neither can most INTEL Macs!
Apple has tons of cash in the bank.
So what's the reason for discontinuing operating support for 2-3 year old Macs again and break a 25 year precedent?
