So far, I really like it. My SIM isn't activated yet so I can't do an awful lot with it phone-wise. I think I'll get it unlocked (if it isn't already) for the moment.
The device feels very premium, much like the iPhone 4. You can tell it's a quality bit of kit. It looks very wide when you actually hold it, but it's only very slightly wider than the iPhone.
The screen is superb, again it's very much like the iPhone 4 screen, extremely crisp and almost AMOLED-like colour reproduction. The keyboard is very nice, but will no doubt take some getting used to.
The phone itself is blazingly fast, I haven't seen a loading screen for anything yet (except the boot up one)! I think the software itself looks very nice and I really don't see why people are calling it 'ancient', Symbian feels ancient, this doesn't.
The camera seems fairly good considering it's EDoF but again, I've not really tested things properly yet. I'll post more later on.
I haven't really finished setting it up properly, nor have I delved into the features, but the first thing I checked is OCUK in the browser and it's VERY good!
There is much reading and fiddling to be done!
