I'm downloading it on to my Netbook now as we speak. Let's see how well Din's chugs on this machine.
-edit-
Ok I tried it on my Netbook. Runs at about 10FPS, sometimes dips lower, but bear in mind this pipsqueak runs on an Intel Atom processor, and uses a GMA graphics card. So, if you have anything better than a Netbook, it should run pretty well.

So when does it actually get released? The demo is fun and I'd probably buy it at $19.99, but would rather do so next month instead of this one.

I don't think a release date has been officially stated yet, but anyway pre-ordering now is as good as getting the full game, since players are reporting the beta version to be very stable.

Yeah I'm sure it is, but being the end of a fairly expensive month, I'd rather wait a month if there's no fear of the sale price ending soon.

Fun game, but I am going to wait for a better sale.

Darn it, I still can't decide. I see myself playing awesome Depths of Peril way more, but ... This thing is just shinier and feels more 'right'. Hmm...

Gave it a go earlier, considering it also has a GMA it runs pretty well. Forgot to look at the fps count.

I'm getting increasingly annoyed with my current town. The monsters just keep having a massive slugfest with one another, and every now and then some douchebag thinks its a good idea to send a bunch of troops to attack the town. The conflicts are insanely hard to resolve, since everytime I kill the leader of a faction, there'll be 2 more uprisings that need to be suppressed.
To say this game is masochistic would be a gross understatement.

Anyone have thoughts to share on the demo? Any interesting encounters/experiences?

I played around with the demo for a little while yesterday and while nothing really odd happened, there were some things that caught me off guard.
First being the massive Diablo fan that I am, having to pay for skill upgrades took a while to make sense to me.
Second I was given a quest at the beginning to head down to level five of the dungeon and retrieve some magical maguffins, however half way through clearing the first level I was informed that the quest giver went ahead and completed the task herself; which felt like the game openly mocking me for my ineptitude. Seriously, why would you give someone else a task that you could do far quicker and with absolutely no trouble yourself, especially if you are going to do it yourself anyway?
anyway those "issues" (and I use that term loosely) aside I did end up having what seemed to resemble fun. I'm not sure whether I will get the full game, at the very least it looks like it could tide me over until Diablo 3

They don't always succeed ;)

Ok, I only tried it for half an hour or so, but what sets this apart from other hacky-slashy games like diablo, sacred, torchlight, etc.? What are the selling points? They elude me for now, but that's probably because I have just scratched the surface.

The randomness and non-linearity of it is its biggest selling point - and I'm not just referring to randomly generated dungeons - followed by its multi class system which allows for different combos (Fire Mage + Necromancer = win, though the pets system needs to be improved on). Third, you're supporting a one-man developer who is just as supportive of his community.
**possible spoilers ahead**
On the non-linearity of the game: to me, every town i.e. adventure is unique. I've had one town where all the factions constantly warred with one another. It wasn't easy to suppress their uprisings, but I believe my killing of their common enemy - the Broods - was the reason why they'd finally made peace. In another town, I had a whole series of mini adventures because one monster faction built an Earthquake Machine that made my life somewhat miserable in the dungeons.
And of course there are the cool little things that happen when you least expect it. Random cave-ins that kill pursuing monsters never get old. Nor does setting a doorway on fire and watching oncoming hordes get burned alive; once, I set a door on fire, and the fire spread to the other barrels in the room, which led to a two rivaling factions inside to roast (the XP gain from that 'mishap' was awesome). And another time, I saw two bosses duking it out; one killed the other, which led to an uprising of rivaling mobs. It's all dynamically generated, and you can practically tell a different story about every town.
Oh, and I really love those town raids where hordes of monsters just come in and start killing everyone in sight, and you know you're kinda screwed when half the population in the town get slaughtered.
I'd love to post more events, but then these are classified as spoilers, so it's best left to yourself to discover them.

For anybody who still cares, the game has gone gold, and I am now a Level 66 Trickster/Gladiator. Fear me, mortals.
