Like your choices except I disabled the dashboard long ago and really don’t miss widgets.

I never thought I’d have a use for Delicious library, but saw a demo of the isight webcam scanning a barcode and pulling up the cover art of a DVD from Amazon and was amazed. Such a good app that Apple hired one half of the development team.

Here’s 3 I’d add:

Senuti – excellent for migrating your iTunes library over to Mac from Win.

Freemind – a nice little mind mapping program (free)

Vine Server – OS X has a built in VNC server that can be activated from the system prefs, but Vine server is much better. I found it’s a great way to get OS X on windows – remotely login to a mac with VNC!
