I'm thinking of getting this phone, it has things i need 4.5/ glance screen.....size not to bulky....but the other windows phone i use 532 4inch has hard keys?......What is better?.....I'm used to texting one hand, and not sure if the on screen will be harder?....Of course i guess the advantage is night time you see the keys on screen right?. I could keep 532 but b nicer to have things that bit larger..... thoughts thanks.
