Not to foreshadow or harp on this, but do you realize that allot of people are turning to technology to help with their gaming? Allot of people are using: palm pilots, Windows CE devices, laptops, etc. at the gaming table. Now if you had come out and said "Hey we got this piece of software, it will fit on your palm or ipaq or laptop and allow you to flip and search through spells with ease and tell you the stats and so forth on them." I would be interested.
Carting around 1lb more of stuff in my already cramped bag is not an option, I have managed to condense all my gaming needs to one device, my IPAQ and it holds everything I need. Seeing this as a solution, why not go that route instead of printing material. In this regard you could get more money for the product, less overhead, and be able to sell it online for allot less. And I think people would buy it.
Printed material is useful for only so much. If you are a DM and you have a cleric and a mage to role play it would be a nightmare to try and sort through what spells get what. Right now I just have the spells listed for each major NPC on my IPAQ in .html format exported from PCGen and I can flip through the books that are needed for now. Would I love to have the OGC of other publishers on it? Sure, it would nice to have Relics and rituals spells listed on my IPAQ tell me what each one did so i don't have to flip thorugh things.
Electronic medium is the way of the future IMHO, print is alive but I hope will not be the ONLY way people get out products much like monte cooks releases on .pdfs.
