There are times when ytou know a niche of customers needs X, but if you build X, they wont' buy it; they _think_ they want Y.
But whats going on here is someone wanting to sell Z because its BIGGER, BETTER, FASTER! Thats bad, I think many/most of us agree .. but I didnt' want to just say the total opposite -- you can't just totally go for exactly what you think people need, since there are outliers, and emotional response.
I mean, same sort of thing that causes an Thingy to sell for $5.99 instead of $6.00; same price really, but psychologically very different. Or sometimes a product colour is lisghtly different or the grain runs a different way, because subconsiously it sells more.
An old example from my home town.. a comic shop had a crummy comic that was reasonably rare, and had a little bit of value due to rarity; call it $15 say. It sat on the sehflf for years, no one buying; one day the guy marks it up to $100 for lulz, and a few weeks later, it sells. Coincidence or perceived value increase due to higher pricetag? (A well known thing in marketing -- higher price can help split you into a niche, evne if you are identical to competitors in every way. Ever heard of Monster Cables?
Anyway, what I'm saying is theres a gradiant along a continuum, like heat; theres hot, theres cold, and theres everythign in between.
You can't focus purely on the utility, or purely on the marketing; I myself think it shoudl be what is needed, but if you have to fusdge specs a little to make it marketable 'at all' or to catch ja few people, thats okay; but when you do stupid things, they're still stupid
