Also I decided to run a battery life test, i quickly chucked together a bit of python to max the cpu out at 100% and then turned the screen on full brightness. The battery lasted way beyond what everyone predicted, infact at 3 and a half hours it still had not even used half the battery life!! that means at least 6-8 hours for a full charge and then its very very unlikely you would run it at full chat on full brightness for 6 hours so probably many many more out of it.
More experiments to come so watch this space!
