This is one of my favorite widgets and a must if you’re a control freak. iStat Pro is the widgetized version of iStat Menus, a system monitor app developed by the bjango.com crew. Seemingly I’m not the only one that loves this (and the rest) of iSlayer’s widgets (Bjango was known as iSlayer before 2009) as they claim that their apps have been dowloaded more than 25 million times.
