XMind -- a powerful, Java-based mind mapping and charting application -- has been open-sourced (it's free!) with version 3.0. While it's not my absolute top pick for mind mapping, it ranks up there. I did have a license for the paid version, and I can tell you that it packs plenty of punch. It has all of the extra features I like: boundaries, relationships, summaries, notes, markers, outline view, floating topics and more, as well as intuitive keyboard navigation for rapid-fire brainstorming.

One of my favorite features was the drilldown; pressing F6 focuses in on the current topic, displaying only it and its descendants. Shift-F6 takes you back up. It's similar to MindManager's "Focus" feature, but faster (and more limited in scope). And for those who want (or need) to, just set all of the shapes to underline, turn on multiple branch colors and tapered lines and presto, you've got an honest-to-goodness Tony Buzan-style mind map ... or as close as you'll get without buying Buzan's software (which, despite it being relatively expensive and lacking in system integration, I am regularly tempted to do) or breaking out the colored pencils.

You can also create Org and Fishbone Charts with XMind. It imports FreeMind and MindManager maps as well as Marker Packages, and can export to HTML, image, Marker Package or Text. The HTML export is ... okay. FreeMind actually creates more useful HTML pages, but it works. Overall, it's great stuff, and it's exciting to see it open sourced.

So, how did software that once cost $299 end up being free? It appears to be a change in the business plan, with a subscription model for "XMind Pro" replacing retail sales. I'm a little sketchy on the details, but the Pro version seems to include online collaboration for XMind users, Gantt charts and a Presentation mode (among other features), with a range of subscription prices: $6USD for 1 user/1 month, $400USD for 10 users/1 year, and everything in the middle. It's not necessary to have a subscription, however, to use XMind. Just download a copy (or even the source code) and let the brainstorming begin. Oh, and tell your PC friends, too; like many Java apps, XMind also comes in Windows and Linux flavors.

John Gruber has penned an interesting observation of how Microsoft might very well have missed the mark from the get-go when they made the strange decision to take on the iPod and iTunes. Since the player's initial wiz-bang sales period is essentially over (as in: it more or less set a decent sales barometer, at least for now), John wrangles some interesting statistics from Amazon's charts on exactly where the Zune stands in comparison to Apple's players (including year-old models), as well as its ranking in the overall electronics category. To spoil the surprise: the Zune isn't doing so well. We've looked at Amazon's charts before, but as of this writing, a record player is beating out the best selling Zune on the electronics list, while iPods - specifically the small, flash-based nano and shuffle - dominate most of the top 10 spots.

John then uses this data and good ol' fashioned people watching to conclude that Microsoft shouldn't have taken what could be their only swing at the plate in producing a hard drive-based iPod; they should have cranked out a flash memory model to go head-on with the nano - inarguably the home run slugger in Apple's lineup. While I tend to agree with John, I also see a problem with going down this road: Microsoft would likely have had even less room to maneuver, and even fewer things to market ('Beam your tunes') and invent lame, dead-end lingo for - they actually refer to sharing your music wirelessly as 'squirting'. Who wants to bet how excited Steve Ballmer's kids are to 'squirt' at school?

Sure, when you look at what you're up against in the DAP market, Apple's iPod nano and SanDisk's respectable 2GB Sansa player (expandable via an SD slot, and at #11 on Amazon as of this writing) are the top dogs to beat - but what could they have offered? I highly doubt they could have fit their DRM-crippled and arguably worthless (though admittedly buzz-worthy) Wi-Fi sharing feature into a nano-sized player, even if they made it slightly larger and uglier like the Zune is to its 30GB iPod rival. A 'Zune nano' with nothing unique to offer would dry up on its own in a market already dominated by Apple, SanDisk and Creative, and Microsoft's exclusive, 3rd party bitch-slap of a music store would have even less of a leg to stand on.

In summary: I think John's right - Microsoft made a bad move in copying the 30GB hard drive-based iPod, but it was the only move they had. In this light, it kinda makes you wonder why they bothered in the first place.

Updates for Keynote 3 and Pages 2 (iWork 06 versions) are available from Software Update. Oddly, they aren't point versions - they're "v2" of the updates Apple released just last week, and they're pretty large. Also, they both have the same description as last week's updates.

Keynote: "This update to Keynote 3.0 addresses issues with three-dimensional charts and textures. It also addresses a number of other minor issues. This update should be installed on all computers that share your Keynote 3.0 files, so that textures display properly."

Pages: "Pages 2.0.1 addresses issues with charts and image adjust. It also addresses a number of other minor issues."

They're both available from Software Update. I'd offer links to Apple's downloads pages, but as of this writing they don't appear to be posted on Apple's site.

Thanks to everyone who sent this in.

Are you curious about the top album on iTunes in Japan? The most popular single in the UK? Switzerland? Then check out this page on Apple's site, which tracks the top tunes in the US, the UK, France, Germany, Japan and fifteen other countries. It could be a fun way to discover some new music.
