The feature-packed iStat Pro Dashboard widget is a reigning favorite here at TUAW, and its recent v3.3 update has heralded some handy new features. First, it now includes (though prompts you to install upon first run) a new module that can read the temperature and fan speeds of Intel Macs. That's right - SpeedIt-be-gone. The other nice enhancement is an active AirPort signal quality meter - the AirPort icon in iStat Pro's network section will now dynamically display a quality meter based on the network you're connected to. Of course, for the record, other bugs and "various minor improvements" made this new version, and it's available either by running the widget (it auto-checks for updates by default), or by heading over to iSlayer.com.
