Quite frankly the unit has to be either pocketable or nearly free to consider a celeron. It isn't just about price Kaido, the celeron is really crappy processor. So while I disagree with your comment in general with regards to the price of the components, the point is that if you are going to spend that much $$$$$$ you should at least get something usable. When we talk about $150 celeron, sure we are not getting something any more useful than the box you spec'ed for $400 but at least it was cheap !!!!. Throwing $$$ into a box with a celeron is like tossing it in the garbage disposal. Sure you make that mistake once or twice a life time but at least it was only penny or nickle; not several hundred dollar bills you were saving for an I3.
The Celeron really is a pretty crappy processor & pegs all of the cores when doing virtually
anything, but it's fine for your average office user. Again, I think the price difference is mostly mental - I'd love to know where else I can buy a turnkey, passively-cooled PC for $400 that is the size of a coaster & can run dual monitors. The closest I know of is the Broadwell HP Pavilion 300-240 (the $249 successor to the much better-priced $179 HP Stream Mini), although that has a fan & vent, comes with half the RAM & a quarter of the SSD storage, and runs at 45 watts vs. the NGC-1's 11 watts, so it's not
quite comparable.
But to your point...if you're going to be paying
four hundred bucks, you'd really expect to get a better CPU. So in that light, in order to explain the pricing, I think we have to look at the NGC-1 as kind of a niche product: if you want a pre-built, dual-monitor capable, fanless Celeron system, then you will have to pay a premium. Otherwise, other great options exist, like the Dell Inspiron 3050, which uses the J1800 Bay Trail Celeron & is currently only $149 at Walmart. I'd hope that the NGC-1's price will come down over time, but since the Z64's price pretty much never budged ($159 for as long as I've been buying them), I dunno if it will. Hopefully we'll see some X5 & X7 boxes that have dual-monitor output for cheap...
