WP:NOTDIRECTORY, , borderline .  May perhaps merit a mention in a more general article about the product family.  There are sites and magazines dedicated to such merchandise which will advertize every product, Wikipedia is an encyclopedia.  It should cover pioneering devices and technology but not catalog everything.  Think about what people will be looking for in an encyclopedia in 20 years from now; they will expect coverage of but the most notable products, those which pioneered innovations and influenced a generation.  This will also result in complete articles which have much to say rather than many stubs
