I am just grateful Apple is allowing the upgrade from Tiger to Leopard, regardless of the "Tiger users need to spend $169" line that I was hearing to date.
"Grateful Apple is allowing the upgrade from Tiger to Leopard"???
They aren't doing any such thing. Read the the license agreement. It says you can upgrade from Leopard to Snow Leopard with the low-cost "upgrade" packs. Tiger users must buy the more expensive "full version" packs (with basically free extra software).
Why should some people pay for Leopard and then Snow Leopard, while the selfish greedy scum skip paying for Leopard? In reality these selfish and greedy scum will as usual use the "upgrade" disc to install from Tiger to Snow Leopard and / or install on multiple Macs simply because the discs don't specifically stop them from doing so. It's called piracy. And then these same greedy morons will later wonder why Apple either doesn't bother to make Mac OS X 10.7 at all, or charges $1,500 for it, or makes you jump through convulted "authentication" loops to legally install it.
You can go out a steal a brand new car for free, rob a bank at gun point, kick small children and animals, etc., etc. ... doesn't mean you actually should do it. Use your brains for a change rather than selfishness!
Common sense and common decency - two things that are extremely uncommon and virtually extinct in the human race, especially on the Internet.
