I'll try to find out about the battery life. Right now that's difficult since I have played around with the device so much, but once it runs out of juice for the first time and has to be recharged I'll try to do a more realistic test with just reading involved.
I'm looking forward to seeing how well this device can perform.
The new and improved software should arrive in 30-45 days according to Staretek and I guess we'll all still be around to see whether they can keep that promise...
