Last year I just bought the bundle, and, oddly, the programs I've ended up using weren't really the ones I thought I'd use when I got it.
I've been having a whale of a time with Macheist, because it started off in early December with a series of puzzle games (the prizes are other free apps, and discounts on the bundle, and things like that). All that is over now but I mention it so that people who like that sort of thing can remember for next year that it's there. I did most of the puzzles with my kids, and they involved things like a treasure hunt in Portland, Oregon using Google Street View, and decrypting code by finding and downloading an Enigma simulator.
The apps in the bundle are: Pixelmator (a Photoshop Elements competitor, but note that Pixelmator has layer masks), Snapz Pro X (flexible screenshots and video capture), CSSEdit (does what it says on the tin), Speed Download (ditto), iStopMotion (easy stop motion animation), Wingnuts 2 (a game, plus there's an extra game bundled in from the same developer), Taskpaper (a very simple GTD app), 1password (password manager that works across browsers), Awaken (turn your £2000 Macbook Air (say) into a £3.99 alarm clock), Cha-Ching (cute banking), CoverSutra (cute mp3 controller) and AppZapper (cute uninstaller).
If that sounds like a good deal for $49, then there's a link here; in the interests of fair disclosure I should point out that that is a referral link that will get me one more app if one of you buys a bundle. But I'm not much fussed about the app; I'm posting because I suspect some of you would like to know that the bundle's available.
