Im a new L1520 user... I was once in dilemma about 1020 and 1520..

In the end, I chose 1520 over 1020

1020 is milesssssss ahead in terms of its camera.. And 1020 has the proper saiz of a phone..

But in price wise, 1520 is worth it.. Its 20mp PureView camera is comparable to its sibling the 41mp PureView lens.. Me myself quite impressed with the quality that produced by 20mp of 1520..

And 1520 has one of the greatest screen installed on a phone. 32gb onboard (+microSD), newer chipset.. And good speaker...

But the downfall, 1520 is just too big.. but my hand can handle it nicely..

So, for me bro, from an owner of L1520, and was once in dilemma between 1020 and 1520 (like you are, hehe), L1520 seems like a fairer choice... :-)
