Maybe he includes stuff like SD cards, a case, HDMI>DVI/D-sub15 adapter and then it can add up.
which in the end make the Pi not so cheap ... it cost same as the concurrent, once packed with what they already offer.
well lucky the Arduino compatibility is here ... even the Radxa Rock Pro has a good GPIO (40pin~ iirc)
I'm surprised that no one brought up the Hummingboard.

It has mSATA, PCI-E mini slot, and a real 1Gbps ethernet port which are some very nice selling points. It's still just a dual-core and 100 USD though for the top-end model.
eh? still a dual core for the top end??? well the Hummingbird A80 i can find where i am is 199chf (roughly 230 USD) oh ... wait Hummingboard ... not Hummingbird (well it doesn't hurt to post it still

1080p@120fps/720p@240fps video coding, provide users a better experience.
High level of integration
High level of integration has been one of the highlights of SoC products, A80 is no exception, the platform integrates an LVDS, HDMI, EDP to make the system design simpler and BOM cost more competitive, products to market more quickly.
Prospect and Purpose
Due to the expansion interfaces of optimus development system are much
more than some other similar products, and it has got global high attention. Thus
making it very powerful, rich social environment and market value. The more people participate, the more rapid development, the greater the potential market, followed by the more purposes. Currently, besides the children's education above-mentioned,it also can be used as basic computer, home theater HD player etc.
