iPhoto is nagging me to upgrade to iLife ‘05

Today, when I launched iPhoto, I was met with the dialog below.

I really want iLife '05, but I'm still bitter that all these Mac tools that used to be free are now more than $50.
Every year.  Plus, you know, I will have to buy Tiger when it comes out.  And I need to get iWork, of course.  And there's also the whole .mac space that I spend over $100 on each year.

With all that, I'm due to spend close to the cost of a new Mac mini this year.  Meanwhile, if I wait until Tiger is released, I can buy that Mac mini and get some of these things (sans the iWork and .mac) for free.

So, please, Apple, either give me the stuff for free or back off and stop nagging me. I'm also irritated that at some point some invisible hand from Apple reached out over the internet and placed this dialog in my iPhoto without any indication from Apple that this was going on in any of their recent updates.

UPDATE: iFelix writes in to note: "You can turn these 'nags' off by turning off the auto-update features of software update. . . . Also the iLife applications such as iPhoto in its preferences, has a checkbox, Check for iPhoto updates automatically, ensure that it is off and you won't see the 'nags' again."
