Recently the Nikon Coolpix s800c (left) was released, it runs Android 2.3 Gingerbread and it has a massive camera stuck onto the back of it. It has a 3.5-inch touch screen and is wifi enabled. When it comes out it is going to cost around £230.
The camera is 16MP and has 10x optical zoom.
This is closer to a camera than it is to a mobile phone however if you want a really good camera closer to a mobile phone then you might need to consider the Nokia Pureview 808 which has been out for a while now but hasn't been received as well as the Coolpix has.The Nokia Pureview 808 (left), has a 41MP camera, a good microphone and records full HD videos. It has a 4-inch screen but unfortunately runs Nokia's operating system... Symbian. Unfortuantely this makes the phone a bit old fashioned. And for around £430, you must really, really, really, really, really like high quality or you would be idiotic to part with your cash.
