Speakers arent that good as 5800....the Nokia Expert at Store himself told me such.
The screen size is better in X6..along with phone memory and capacitive touchscreen + better camera....rest, everything is same as 5800
The speakers are as good as 5800's, a firmware update fixed them. The built-in amp of the x6 was not configured to cut off the bass frequencies resulting in more power consumption and distortion.
And both 5800 and X6 have the same LCD screen and same screen size(3.2 inch), the only difference was in the touchscreen technology.
Apart from touchscreen tech., camera and memory there is not much difference in their hardware.
And the people at stores are not experts, they don't even have knowledge about the phones.
They lied to me that 5230 was stopped due to software issues and I had to buy 5233(2 years ago), about a month ago they told my friend that Belle was not coming to older Symbian^3 devices including my friend's C7.
Real experts are here, in this forum!
