Similarity in meaning is not always good. DigiCamera works well as its a common accepted phrase. DigiBonde does not work, just like DigiTV, you can look up the overture on that one if you like.
P.S: I was questioning 'many other similar names are available'. So far you have only one example of similarity and not a good one at that. Where does 'namy' come in?
I do respect all appraisals, but if you are going to post a reason, at least post something real. I dont even ask for reason and take $0 appraisals without any problems. In this case, something like "no business development possibility" or "limited development scope" would have been cool, but if someone posts 'many other similar names are available' i simply have to ask for a few examples, to educate myslef in the matter if for no other reason.
