"Problem: I recently bought an old G4 Quicksilver with single 867 MHz cpu, running OS X 10.4 Tiger, and LOADED! with applications such as Final Cut Pro, Final Cut HD, Adobe Photoshop, CG3, MS Office for Mac 2008, etc., but no installation disks."
The last few words are where we see that you didn't obtain such legitimately. Sadly there are folk that sell machines "loaded" and the message is not sent along that you don't have the rights to such software.
If you did you would have all your product keys and CDs. If you had proper rights you can get replacement install media for cheap.
Hope this clears this up. Bob
Subject: You are absolutely wrong
Regarding your erroneous allegation that transferring applications from ONE computer to ANOTHER computer constitutes"casual piracy", case law in both district courts and state courts says otherwise.
First of all, most - if not all - EULA's grant use of software on A SINGLE COMPUTER, not a SINGLE USER. As I am the legitimate purchaser of this computer, I am the legitimate owner of the license - whether or not I possess to installation disks. The individual who sold the computer is the one who is in violation of the EULA's if he/she has it installed on another computer.
Secondly, the First-Sale Doctrine, established by the US Supreme Court in 1908, and upheld in many state courts since, establishes that computer software is a product, not a license, and may be re-sold.
Thirdly, in Softman vs. Adobe, the US District Court for the Central District of California ruled in favor of the Plaintiff, establishing that, since the Plaintiff, as a secondary user, had not installed the software himself, he had never agreed to the terms of Adobe's EULA and was, therefore, not bound by it limitations on use.
I don't know what you do for a living (other than "do"), but I happen to be an attorney not unfamiliar with copyright law."
