Have had this phone from Play (very, fast efficient service as always) and can honestly say this is probably the best phone i have had to date.
The phone is easy to hold, the rubber texture on the rear panel makes it hard to slip from hands as opposed to my other android phones. It may polarise opinion to look at initiially (i didnt like it at first) but it looks pretty cool now lol.
The screen is brilliant. Not so great in sunlight but i can live with that. Updated to android 2.3 straight away. Battery life is pretty good, 2 days with moderate use. I normally play my music at work on our stereo and 8 hours later only down to 50% and thats with google sync still on.
Web browser is fast, Audio both in call and through headphones is very good. GPS also very fast to log on to as well.
Have experienced no crashes or lag issues. Very smooth HTC Sense interface. To be honest I'm not missing any of the dual-core hype at present. I have a motorola xoom for that and even then there arent really a lot of games/apps utilising it.
Would highly recommend this phone.
