While I'm still a bigger fan of the iStat pro
widget, miniStat2 definitely wins points for compactness, creativity and for quickly incorporating a monitor for Intel Mac temperatures. Other updates include the ability to change the currently monitored network interface right from Network tab of the widget, the storage tab only displaying physical hard drives (as opposed to including .DMG files and the like) as well as a Spanish localization.
A demo of miniStat 2 is available from ShockWidgets
, and a license will cost $5.
