I'm using Galaxo 1.6.1 for 2 days now and I think it is a huge improvement compared to the 1.5 firmwares. Touchscreen is much more responsive, battery endurance is better, more apps are supported and overall responsiveness has improved.
Does any of you by change have tested if Wifi Tether is working with this new firmware? See:
