The iPod touch upgrade: Are they bugging you?

Did you upgrade your iPod touch? I did. But I presumed it was optional. TUAW readers who have chosen not to upgrade report they're being hounded. By iTunes. They say that every time they connect their iPod to iTunes for syncing, they're getting hit with a "buy the upgrade" page that only has an OK button. Once clicked, it transports you to the iTunes page for buying the software. Is this happening to you? Are you feeling strong-armed into buying the upgrade? Let us know in the comments.
