LogMeIn Ignition, a $30 iOS app that allowed users to fully access and control unlimited numbers of Macs and Windows machines from their mobile device, has effectively been superceded by a new, free app simply called LogMeIn from the same company. However, Ignition users will now be automatically upgraded to the feature set of LogMeIn Pro, as well as enjoying a new HD streaming audio and video feature that is set to debut in early 2012.
