Looks nice, but bloody PMOD or even worse Arduino connectors that are not even aligned to 0.1" - somebody has to stop this stupid trend. I was considering once to buy STM32F7 Discovery board and it also has only Arduino pins broken out (and on the bottom side!). Fortunately STM32F7 Nucleo has two normal dual pin header footprints (but in addition to something Arduino like )
I'd rather see all the pins (except really commited ones, like the DDR memory etc) broken out onto 0.1" or some high speed connector, this is particularly important for the FPGAs.
Something like an FMC but cheaper? I might know something in the works like that.
It baffles me, full blown dev. board has more connectors, components, features, accessories and is still cheaper than a SoM which is a tiny PCB with FPGA/CPU + SDRAM/FLASH, some power & clocks and 2-3 high density connectors or even cheaper - SODIMM 204 pin edge connector.
I didn't see that board at Digilent but I did see a more affordable Zynq board:

Not cheap but it might be worth it for the education.

Not cheap but it might be worth it for the education.It is worth noting that Digilent also offers the Pynq-Z1 for only $65 with the academic discount. It is a hardware equivalent, except it additionally has a PDM microphone.
This is good because while there isn't any support for non-pynq software on the pynq, all of the support made available for the Arty will be directly applicable.

Alas, I am not eligible for an educational discount and nobody seems to offer an 'old geezer' discount. Bummer!
Of course, with the Spartan 7 costing $300+ alone, it is safe to say everything mentioned is going to be cheaper than what we see in the OP.

What are you talking about? That part on Digikey that someone posted is $18, not $300+.

I think Mike of mikeselectricstuff is a big fan of these: https://www.digikey.com/product-detail/en/Lattice-Semiconductor-Corporation/LCMXO3L-6900C-S-EVN/220-1935-ND/5039065 but I have no personal experience with them.

I don't quite see the point of the Spartan 7

$18 looks substantially cheaper than Artix-7 to me. I'm not sure how real these prices are.

The guy in the video says a Microblaze soft processor costs as little as 19 cents to implement in a Spartan 7 FPGA. Does he mean the cost for IP or the cost for both IP and the logic fabric that it will take up? 19 cents seems pretty low. The only device I can get a price on is $18 for 6,000 LEs (link above, the only part listed at Digikey, though not in stock yet). A minimal Microblaze is said to be around 600 LEs, right? So that is $1.80 in fabric for a small device. Do larger devices really lower the price by a factor of 10?

They're probably talking about whatever device is the sweet spot for lowest cost per LE, and also probably in quantities of 1,000+. You're always going to pay more in single quantities and quotes like above are aimed toward mass production.
