As a satisfied owner of a Huawei G300 this looks pretty good. The build quality of the G300 is excellent and the battery life is much better than my old HTC Desire. I used to get about 1 possibly 2 days out of that old thing when it spent most of its time in my jacket pocket, even with HTC Sense removed, CyanogenMod installed and data/GPS/WiFi turned off unless needed. The Huawei I'm on now I can get a full working week, using it for music and light web/e-mail.
If this P6 can buid on that then I'd be tempted if the price is right. If this is the slimmest phone ever I bet the battery life will be dire though.
I can't say I'm concerned about the prospect of the Chinese possibly being able to access any of my data. Google already have their fat fingers throughout Android, my network operator probably does whatever it likes for the UK gov so I may as well help the Chinese along a bit as well since I have no particular fondness for any of these three countries.
On a vaguely related note, it's a disgrace that you can get phones with resolutions equal to or better than most laptops. I just do not understand why it's so hard to get a laptop with a resolution better than 1366x768 for around £500 or less. Just a half-decent screen resolution please. It's annoying that I can't find much better than my 8 year old Asus with 1680x1050 without spending £800+. Yeah I know, these first world problems.
