“Likely to encounter issues for which there is no resolution.”

From Adobe’s summary of software that won’t run under Mac OS X 10.5 (Leopard).

Translation: You’re screwed, sucker. Buy an upgrade.

If they’d said something like: “Look, this is old software and we can’t afford to keep every release we’ve ever issued up to date”, then that would have been fine. It’s the impersonal “issues for which there is no resolution” that bugs me.
