Did you miss the part about "bundled" vs. OEM?
Bundled software (or called OEM in the case of Windows operating systems - most companies don't use the term) is sold bundled with hardware and the licence prevents the sale or resale of the software separately from the hardware.

Plus, pointing out that Microsoft OS's can be called OEM if bundled, in no way invalidates that statements that:
1) Adobe software is not sold separately as OEM, although in some cases it is sold bundled (see above why that still doesn't matter)
2) "OEM Software" is a long-abused 'excuse' for software pirates.

Most software advertised as OEM are not actually genuine OEM disks being sold illegally, but are flat out copies. If you doubt it, I will forward you the 50 or so emails I get per day offering me OEM sofware for $9 per disk.
Just like the $800 MacBook Pro machine that is being sold on every craigslist in the world -- if you could dredge up one instance of a real MacBook Pro having been sold for $800 somewhere, it does not mean that the other 99.99% of them are not scams.
Aaaannnddd... if bundled software is sold on, it would not be 'legal' in terms of the EULA, and it would not be upgradeable or possibly could not be activated (depending on the software company). In most cases, the terms of purchase for the software specifically prohibit resale or transfer, regardless whether it was ever installed on the original machine or not.
But we are arguing (needlessly, endlessly) over terminology. It's $1800 software being sold for $300. Of course it's a %&@#ing scam. Tristan, you really shouldn't have had to ask.
