how is it compared to the D500? I have a D-508 and was checking this one out. Any real differences or advantages to this one?

 

everything that d500 has this one has with improved everything. from music/ringtones to picture quality...you can sorta already tell from the wallpaper i have on the phone, it's crisp like a real camera. it's like a motorla razr, but it sliders. the screen is bigger. the phone is slightly taller and wider than the d500, but thinner.
