I'm glad that you found the article to be of use. To address your question: yes, I find the information is still current. I still use the same programs described in the article (with a few minor modifications). What follows is my current setup. I have been using it for nearly two years and I'm very happy with it. It covers my collaboration, calendar, tasks and file sync needs. And most of it is free (with the exception the Zimbra services that I receive through my webhosting company).

Calendar (Primary): Zimbra Collaboration Suite. Zimbra makes a plug-in that works with Microsoft Windows (Outlook). With the plug-in, it behaves identical to MS Exchange, which is to say, a full-first class citizen in Outlook. It can be accessed via iCal (Mac OS X) or Thunderbird (Cross-platform).

Zimbra has full synchronization support for iPhone, Windows Mobile, Palm Pre and Android. I have used it's iPhone support, and it is fantastic. The only thing that I miss is task sync (which is a full-post rant on its own), but that is a limitation of iPhone, not Zimbra. Unfortunately, the future of Zimbra is somewhat uncertain. They were recently purchased by VMware and it is not clear how their platform will evolve over time.

Calendar/Collaboration (Secondary): Google/Google Sync. In addition to my main calendar, I also keep a secondary project based calendar through Google. This is used for scheduling meetings and collaborating with others. I use desktop personal information management software (PIM) in order to aggregate my Zimbra and Google Calendars in the same place. GCal also works with iPhone and can be accessed via Google Sync or via WebDav.

Contacts/Tasks: Zimbra Server. Support through Outlook plugin and Mac OS X plugin. Thunderbird plugin also available.

Data: I've been using Windows Live Mesh for the better part of three years and I've absolutely loved it. It is fast, robust and comes with a large amount of free storage (4 GB). The only limitation is that it is doesn't have a Linux client.

An alternative is DropBox, which I've also used. But because I had few early problems with their Linux client, I stopped. On Linux, I use Ubuntu One (though primarily for online backup). In addition to the cloud offerings, I like to use a personal Subversion server for filesync. By using a central server, I have a backup of my version controlled files and I can keep in sync between my computers.

For photo sharing, I primarily use Facebook, Windows Live or my personal web-gallery here. Flickr is also nice, but I'm not a big user. Since I use Lightroom (which has export plug-ins for all of these), it is easy to export pertinent photos to the appropriate service. I do not attempt to backup photos online. Rather, I have a dedicated drive on my server and use Rsync for that.

Hope that helps.

Cheers,

Rob

I use SyncMate free Edition(allows syncing contacts and Calendar) and it works great for me. They also have Expert Edition - it is paid but offers more sync options like iTunes, Video, iPhoto, Mail sync and lots more. Details can be found here http://www.sync-mac.com/syncmate-features.html

I work with large CAD drawings, and use MyOtherDrive's file sharing instead of trying to send them via email attachments. I can upload any size file, and then create a link to it, and just email the link. I can set this up for private access where only my associate can get the link - very handy. Definitely worth a look.
