Isn't the Pi incredibly underpowered for use as a compute node?

Yes, but the graphics part is pretty good (especially compared to the raw 'CPU' part). I'm seeing this as just the same Raspberry Pi without the specific form factor of the original.

I'd like to think that someone can make something that looks like a smartphone with this.

For standard 'computing', yes.

However, I have several that I use for single-purpose tasks and it excels at this. I have one Pi in my office that runs tmux/mutt/irssi, so I can easily access email and our internal chat server from any computer in the building.

I have another hooked up to a TV that acts as digital signage, showing uptimes and other system info.

Pretty neat stuff, but it's painfully slow for GUI tasks

This is very interesting in regards to a having cheap Linux SoM (system on module) for businesses to use in their products as well, by far the cheapest I know of with these specs. Doing routing and verification for a chip like that is no easy task.

I'm really curious to see if the foundation will commit to a product lifespan / availability for commercial use. If so this could become pretty big. Obviously if you are selling a product in 100,000s+ you will probably roll your own, but for a small business to produce a niche product that's going to be sold in the high hundreds, or product a proof of concept this is awesome.

EDIT: rereading the blog post, this is aimed at commercial use, definitely great in regards to pricing, however, I wouldn't want to base a product on it without a guarantee of availability / compatibility from them. The Beaglebone black specifically says that they don't guarantee compatibility between revisions for this reason.

I'm a little disappointed that this isn't a compute-addon for the rPi that gives it some serious calculation power. Ah well .. guess I'll stick to the IMX platform for that ..

Well, the existing RPi's GPU has 24 GFLOP capability, which is roughly the same as the GPU on the baseline i.MX6 (the Vivante GC2000).

Now, a lot of that capability has historically been unavailable to RPi users, but they're slowly responding to pressure and opening up the GPU.

But I also saw the headline and was hoping for some nice little GPU compute add-on the RPi. Oh well. I still think this is a very promising form factor for the RPi.

That was the first thing that came to my mind too.

What kind of hardware specifically were you expecting and what kind of acceleration hardware there is generally available for these kinds of applications?

Earlier quoted context omitted.

First impression: Improv has still all those bulky connectors on it. Second impression: It costs twice as much as the RPi module.

I think those connectors are on the detachable baseboard, not the processor board.

It seems you are right. In that case it is more comparable to this RPi module. The price difference stands though, if you can't get the processor board separately significantly cheaper somewhere.

It's about time they put some FLASH on-board. SD card has proven time and time again an unreliable medium. You never know if the device would boot up after a "dirty shutdown"

Personally, I liked the SD Card method. It allowed me to keep a few cards with different OS images on them, and quickly swap them out when I wanted to change what the device was used for.

It might be a bit more difficult with the built in storage, but I suppose it's nothing that can't be managed.

Very interesting. Definitely makes integrating the Pi into projects a lot easier. The form fact will help with making things smaller and reducing a lot of external connections (gpio breakout, Gertboard,...). I'm interested and ready to buy!
