I’ve started building a list of applications that fill me with joy.

• LaunchBar – can’t imagine life without it.
• xScope – I don’t even use it that much, but when I do… so awesome.
• Pukka – I’ve been using Delicious as a central data store more of late.

These aren’t all “must-have” apps, nor are they the ones I use most (if it were, BBEdit would be at or near the top). These are apps that meet or exceed my expectations every time I use them; and never give me the “if only it would…” thoughts. I think the common thread on these is that my usage of these apps is not as deep as the functionality each app provides.

What’s on your list?
