hmmm, I am interested in seeing more detailed battery life information including for more "active" use.
http://www.getinpulse.com/faq/ The first question under Inpulse category will answer it. That's in case you haven't seen that one already.

Yup, but we've got Bluetooth, a fantastic OLED screen, and example Python, Android, Blackberry code! Also, we're right here on HN to answer your questions!
What are the dimensions? (I'd love an accelerometer - sure you guys are well aware of the possibilities)
96x128 pix full color OLED display

#33I am totally getting one, soonish. I confess, i have a Watch fetish :(
Better get one quick! First batch is moving...

#34Does this run multiple applications or do you have to plug it in each time you want to run a different app?

#35The devices look cool from a technical perspective. It could use a few more sensors (GPS, gyro/movement, temp, etc.) but I'm sure that will come. The only problem, I think, is that they're not very stylish. A bit too large/clunky looking. I'm not sure how to fix that while keeping the display a useful size. But that what geniuses like you guys are for!
I think these look much better then putting the Apple Nano on your wrist: http://bit.ly/hnLUkQ To each their own though. =) As for applications, yeh GPS, Gyro would be great.
Here's the TikTok/LunaTik link: http://www.kickstarter.com/projects/1104350651/tiktok-lunati...
They raised $941,718 from users, so there's definitely a market for style. It's touchscreen, costly (nano+holder) and non-hackable.

#36For comparison: Texas Instruments sell something called the EZ430 Chronos watch, which has a much lower-res display, a proprietary RF protocol with a USB transceiver, and a bunch more sensors including 3-axis accelerometers, pressure and temperature. It is based on the MSP430 microprocessor which is much less powerful than this thing, its capped at 16mhz or something IIRC and only has around 8K of program space. It i…
It is interesting to note that the EZ430-Chronos can last about 6 months on a charge if continuously reading BlueRobin data (which is a one-direction wireless data) while this inPulse aparently can only last 2 to 3 days recieving data over bluetooth.
Less powerful processor and cheaper display might be a good thing, depending on your uses.

#37Wow, I love it! Seems like a great gadget; I'll be purchasing one.

What's the actual hardware inside? Do you expose (quasi-)standard ARM JTAG?

One app at a time, right now...but we're working on getting multiple apps running as well! Good point.

From http://www.getinpulse.com/faq/
What is the battery life like? With aggressive power management (turning the screen off most of the time and leaving bluetooth disconnected), it can be up to 3 days. If bluetooth is constantly connected with the screen turning on periodically for alerts, you can expect 25 - 30 hours. If you have a processor-intensive application and are using the full capabilities of the screen non-stop, you can expect 2 - 3 hours.
So unfortunately it seems that the battery life is the biggest issue with inPulse
