The PPS is not always tied to one set of criteria, as this stock has certainly demonstrated over time, as well as the overall markets at large.
EDIG is executing their current business model and when they are debt free and flush with cash they can grow via acquisition over night, as well as further develop their eVU business...not to mention continuing revenue generation via their intellectual property strategy.
It's looking like it's just a matter of time for new investors to recognize that and seize the opportunity.
Imagine having the opportunity to own EDIG at .11 in 1999.
Do they look suited to exploit another market opportunity today? Not only would I say so but there is proof in the form of LG, Casio and NIKON.
