Sorry, but I didn't understand any of your points, but I can guess..? HardKernel's N-1 is aimed at being a 4GB fast ARM platform that exposes as many of the capabilities as the SoC can deliver. Doing it cost competitively seems to be the main challenge, although their delay to August isn't explained so they may have other challenges. Assuming they get the N-1 to market, their investment is in terms of board design, production, and software/community support. If there are variants possible which don't require more engineering on their part, this ought to be an attractive option to potentially expand their market. Thus if the NPU-equipped SoC is a simple drop-in replacement for the non-NPU one, then this seems like an obvious win to maximize their design investment. That NPU is quite a monster (for this class of SoC), and the software support for it seems to have been done already, so it brings new capabilities that ought to expand their market reach somewhat.

seriously you guy`s the going price for an "XU3" was around the 170 usd or maybe aud i dunno but if i remember correctly...long time since i brought mine....either way people bought the xu3 or the -lite..weather h-k bring`s out an "N-1 -lite still remains to be seen.....

...yet there is a lot of.."whining" about the price of the "N-1"...

y is this...

my 20 cents worth...phase

I said something similar in another thread. The thing is there are many powerful devices in this sub $100 space now, even more than when I said this very thing.

In my opinion it makes the XU4 even more attractive for many. But I know the Exynos 5422 is EOL and stock has to be running out, we need something to fill his shoes. The N1 is it.

In my opinion, the estimated cost of N1 is cost competitive:
Firefly RK3399 (4GB) = $209.00
RockPro64 (4GB) = $93.47 (SATA + Heatsink are extra)
N1 (4GB) = $110 TBD

Firefly = vendor support (effectively none)
RockPro64 = community support
N1 = vendor + community support

I only for the support of hardkernel and the community I choose N1

my 20 cent`s again

furthermore h-k needs to make a profit as well as producing and supplying the N-1...

the said price of 110 is just covering the cost outlay for the parts..
and many would still buy the N-1 at a higher cost..
as to say that h-k doesn't need to sell themselves short
they should be making a profit... what that margin is...
only h-k can determine thus ..

I'll pay what is needed for them to profit, as well.

I agree insofar that I will pay more for an HK part than for one of their competitors with an approximately equivalent part. The more they can drive their costs down, the better. It improves their position in the market and/or increases their profit margin.
