WARNING! in my opinion you should avoid this stock like death. the company has a much hyped "operating system" that they have been touting for YEARS in order to sell shares to their "friends" who then dump them on unsuspecting shareholders. The operating system is called "MicroOS" and amost NO companies has seen any value in licensing this tech. A few companies such as Bang & Olfson did license MicroOS when it was THOUGHT that it might be an important tech. 3 years ago but it has proven to be unimportant. At any rate the royalties received from the minor licensing deals is almost impossible to find in any of the financials. Also, the only well reviewed product they no have is a 20 gig music jukebox, however there are cheaper better products out there and the market is crowded with well financed branded competitors. EDIG also has almost no money and has to sell shares to unidentified off-shore entities in order to keep the doors open.
