I realized I have a few apps that are now rare collector's items. The four apps in my dock in the screenshot are the four apps that I heard were pulled from the app store.
For accuracy's sake, PhoneSaber was pulled by the developer (though not before was threatened by THX (LucasArts?)).
Surely, there is a market for breaking the DRM and trading these on a (as far as I know) theoretical site called something along the lines of "the pirate bay"...
How long until all OS X developers start signing and encrypting their apps for the Mac?
postscript: Speaking of iPhone apps and Netshare... the WordPress app was unable to post the photo and couldn't post the text without screwing up the formatting (and don't get me started on WordPress in Mobile Safari), so I ended up launching iPhoto to grab the screenshot, and firing up Netshare to post this via Safari.
Don't be fooled by the "No Service" in my screenshot, I took that in the bus tunnel under Seattle.
