Ah. Thanks for the link.
The 149$ version comes with Windows 8.1 Preloaded. The linux version is 89$.
Edit: I see there's a hardware difference too. That's a bit of a shame. I wonder what corporate forces are in action here..
I doubt it's actually that much of the price tag.

Eh, the hundreds of hours I spent learning Windows were much less useful to me.
Basically, the difference in price between the two SKUs is purely hardware based. So, buy whichever hardware you need, and install GNU/Linux.
On a side note, I have an HP Stream 7 tablet with an Atom CPU and 1GB RAM, and it runs 8.1 very well. I'd imagine even the lower spec SKU of the Intel stick would run it fine. Storage space would be the only real issue for that OS.
