Yet another OS X app list, with a corresponding thread on MacSlash. Mostly boring, but a few things I hadn't seen before:

• NetFlix Freak, a full-featured NetFlix application that lets you search and browse the NetFlix catalog, and manipulate your queue, faster than with NF's web site. $15.
• Vektor, a chess program with some nice annotation and output features. $19.
• Enigmo, a 3D puzzle game. $20.
• iPick, a color picker. Free.
• Unison Usenet newsreader. $25.
• xScope, screen tools for designers. $15.
• Cocktail, a GUI frontend for a bunch of system administrative facilities. $15.
• skEdit, a text editor for web developers. $20.
• Smultron, a text editor. Open source, written for Mac OS X natively (Cocoa). Free.

Delicious Library ($40) and TextMate ($50) have both had a couple of months to do post-1.0 bugfix releases, they might be worth a second look.
