I have Nokia 770 tablet at home. It is mainly used to play Maemo Blocks, Mahjongg or other game. From time to time I use it to browse web or read RSS feeds so it is non-stop connected to my home WiFi.
But today I had to charge it in the morning and after that it died after 2-3h of playing. I do not know how good is N800 in this subject but hope that next tablets will have better battery life as this one has it too small.
Maybe it is because of OS2007 but older releases did not fit my usage.
I hope that one day I will be able to use Ångström on it. But do not know how many base components are close sourced.
The sucky battery life is due to the ‘hackers edition’ you have installed, the original OS has a lot better batterylife.
