is meh.
Finally made the plunge...
Switched from Nokia N8 to this... and I find symbian Belle more user friendly (easy) to use.
The SNS integration on this one is pretty good, and the overall performance is way ahead of N8, but... maybe it's just me, I find it a bit confusing as compared to Symbian...
I thought the same about Anna vs. Sense 3.0 on the HTC Sensation. I'm on Windows phone now, I think it offers the best SNS integration in its People hub, and is more consistent & faster. But I guess the SGS2 will get ICS which should improve things, with some touches found in WebOS.
