Hi there,
Managed to get around 1.5-2 hrs of usage before total battery depletion. Did some web surfing using wifi & music/video listering simultaneously while running Columbus via bluetooth. So far no problems arose during the abovementioned test run. No disconnection or lag etc... Upon finishing recharging back the batt, restart back Columbus to see if any problem arose because of improper shutdown. All I can say is that Columbus seems to be running ok.
I did notice 1 thing though, my N900 did became a bit hot. If i scale 1 to 10, it would be around 7-8. That hot. While testing, i did OC to 950Mhz with active animated livewallpaper. Wonder it's because of my OC'ing?
Anyway, my report is that Columbus seems to be running rather well on my end. I'll post here for any updates/faults/hanging etc,.

Sincerely,
