This weekend I bought and rooted a Nook Simple Touch. The reason? I’ve been looking for an eink platform that one could make astronomy applications and data available for. Eink is ideal for a hobby where stray light destroys your ability to see anything.

Having written an astronomy application (albeit one that needs a lot more polish) I pushed it over. There are a few rendering issues with the buttons (which completely confuses me), and the fact that there aren’t any real location services means rise / set times are completely off, bother are fixable in software. Computational speed seemed on par with my HTC Evo, which means this is something I can work with.

Sadly, both B&N and Amazon have equivalently limited imaginations when it comes to making Apps for their e-ink platforms (my Amazon knowledge comes from email exchanges with the Kindle team), and don’t see the other possibilties for e-ink.

Fortunately, B&N seem to be lacking on having a crack security team, so the Nook ST can be wedged open to an open platform pretty easily. I’ll be making Where is Io optimized to run on it, and look at what it would take to get Google Sky Maps over there (now that it is open sourced). And, I’ll hold out a small amount of hope, that B&N one day figures out it might be useful to provide this additional value to their customers. Based on email exchanges with Amazon, I’ve completely written them off.

Key Takeaway: don’t let your own limited imagination, and need for control prevent your creations from meeting their full potential.

Update: now that the Android Market finally activated, I pulled down a number of apps to see how they all worked. The Mobile Observatory UI is actually really useful on this size and type of UI, and I think is worth the price of the Nook Simple Touch even if you only decide to run it.
