2. With real (high-tech) products, as nicely pointed out by RB a few posts below (or just check out the web site).
3. I was following the company for years, and trust they are at their turning point: less R&D, more sales.
4. Any way you look at it, this is way undervalued at this point. Check out the Price/Sales indicator, and you'll know what I mean.
Opinion: Unlike another good PR comes out (which I won't be surprised), the price will still be below say 0.003 or so for the remaining of this year. It simply has to do (as allways is the case) with year end tax losses. Comming January, this should start moving; the real move, that is.
