The name Collusion elicits negative connotations and my initial reading of the title led me to think that there was come wrongdoing on Kickstarter's part. I really would reconsider the name of the name of the company / product, unless this is the intended effect.

I really don't get the name at all. You wouldn't call your product "Insider Trading" or "Price Fixing" – why is "Collusion" any better?

The video still shows a lot of lag between when the stylus touches the glass and the pixels in the app show the pen trail. This needs to be heavily optimized or else it will make their hardware a lot of engineering work for nothing and users won't be happy. At this stage, from the video, it looks to have similar latency as other existing iPad sketch apps and those have no hardware dongle or stylus (and cost $100 less…

There is no way to optimize it as the matter is out of their hand. Its just the delay for input events to go from hardware to kernel to user land. MS Research had a neat demo on this very topic some time ago. Edit: never mind, it seems they use their own hardware. In that case, it would be interesting to know if iOS allows fast raw access to the external periphery.

Lag = fail. Interesting since it seems they use the dock connector so you would assume that there would be minimal lag compared to say Bluetooth.

The Inkling looks interesting. The Verge gave it a 6.8, which isn't too too reassuring. The thing with the smart pens is that they're chunkier than I'm used to, and then I worry about the smoothness of the pens. I know the LiveScribe doesn't have gel based ink refills, which is basically the only type of pen I write with. I find the friction from normal ball point pens a little uncomfortable.

You should honestly consider purchasing a fountain pen. They work via capillary action, which means that they write on contact -- no pressure needed. At all. Some good starters are the LAMY Safari, the TWSBI 540, and the Kaweco Sport. All of these cost I, too, used to think gel pens were the bomb, but writing with a fountain pen is just something else. :D

That's very informative, I think I'll give a fountain pen a shot.

It's a neat idea, but the lag is a dealbreaker for me. I've been looking/waiting for a pen based note-taking solution, even if it's a unitasking solution, to get rid of the heavy hardcover sketchbook in my briefcase. My use case is simple, I just want a digital copy of my notes -- I don't need any OCR or anything fancy like that, and I'm not convinced that a LiveScribe is the way to go. I had high hopes for the NoteS…

Camscanner + regular pen and paper is solution i'm currently using. I use camscanner to create a PDF version of my paper notes.

Livescribe works pretty well.

Unless you're left-handed :-( Then you spend your time scratching and pushing against the paper and smudging your handwriting :-(

If you're trying to do mirror writing they become awesome again, but that's not a frequent use case:-(

Ah yes, I remember this. Worth noting that his device is a projector putting the image on a screen, and I think it's got a lot more computing power behind it than an iPad has available.

The current latency isn't a CPU issue though. I'm not sure of the refresh rate of the iPad (60Hz?) but the hardware has no trouble updating the display in a single frame. It should be noted that unless Microsoft had a 1000Hz display running, there was something fishy going on with their 1ms update.

From this high speed video I took I think the refresh rate is 60Hz (this shows it is at least 60).

I asked about the lag and they responded with this tweet. https://mobile.twitter.com/#!/collusionapp/status/2083668457...
