:: The whole *point* of consumerizing a product is to simplify the consumer experience. "Building a Heathkit" to start using a product is not a typical consumer experience. Henry Ford didn't make his fortune selling assemble-it-yourself kits to consumers.  
 :: I would have thought  "being marketed to homes" was subsumed under "mass market consumer product" (durr!) but maybe this isn't clear enough? Commodore probably sold more VIC 20s in an average week than the entire production run of H11s. With a home computer, you plugged it into the wall socket, unscrewed the rabbit ears, borrowed your sister's cassette deck and away you went. WIth the H11, *first* you had several evenings of assembly to go through, *and* you ordered a teleprinter or terminal, *and* you had to buy the $325 punch or the disk drives, *and* you were buying minicomputer sofware from DEC at minicomputer prices - to get the functionality that a TI 99 had out of the box. 
 :: Care to estimate what the mean time between opening the box and a scrolling display of "Sister Stinks!" enlessly scrolling down the screen was, for the case of a home computer and the case of the H11?   
 :: The machines in the "List of home computers" fit under the defintion given under that lists's lead section, with the notable and singular exception of the Honeywell "Kitchen Computer" which is only an "honorary" home computer.  It was stone useless in the home, of course, but it gets on the list because it was the first one "marketed to homes".  
 :: I don't recall William Shatner or Bill Cosby shilling for Ohio Scientific or any products like that.  At least the ZX80 kits were advertised in consumer publications.  

 ::Do you not remember the extraordinary claims made for home computers at the time? There was a strong implication that if you didn't give up TV watching time to the 6502 box with a cartridge slot, little Junior would grow up semi-literate at best.  
 :: I think it's extraordinarily Wikipedia-ish to cling to the word "home" in one ad, instead of looking at the actual product.
