One of the major things I miss about switching away from a Windows Mobile or even Sony Ericsson mobile phone is Salling Clicker - just about the best darn software I've ever seen for controlling your Mac with a mobile phone or PDA. Clicker offers a wide array of customizable controls with which you can enable your device to control everything from iTunes to Keynote, and even do things like pause music when a call comes in or lock your display if you walk too far away from your Mac. While I cross my fingers that Salling Software can create a BlackBerry client sooner than later, the rest of you can enjoy today's v3.5 update which ushers in a slew of new features and wider support for yet more devices.
At the top of the feature list is support for Front Row, potentially eliminating the need to pack an Apple Remote when venturing out. Other new features include: improved iTunes functionality with quick access to current playlists and more browsing options, support for Windows Mobile 6 and Symbian 9.x devices, much easier Wi-Fi connections for Symbian and WinMo devices, improved Keynote and PowerPoint functionality and much more (I should also note that Salling Clicker for Windows now supports Vista as well).
Check out the main product page of Salling Clicker for Mac if you're new to the possibilities of this excellent software, or take a look at the v3.5 press release to get a look at what's new for you seasoned clickers. A demo is of course available, while a license costs a mere $23.95.
