I have Lumia 620 in a white .... First thing it looks amazing ...... Dont get carried away by that . This colour attracts stains very quickly ...... After sometime it looks dull... Brownish in colour......If you want to showoff your white Apple friend .Then its fine ..... It looks Classy though .....
Good: Moved from black to white. Makes Lumia 620 look like more premium device than it was before. Black camera lens and black buttons did great job in providing contrast to white back.
Bad: Gets dirty easily if not taken care. And once yellow marks appear on the shell, it never goes.
