I've always loved the build quality of Lumia phone and am actually thinking about switching to WP when I'm able to ugrade (currently on a BlackBerry Q10). My only real issue with most flagship Lumias is that there is no SD card support. This is a big deal for me as I have a lot of PDF files and an SD card is a must on any phone I buy. So I ask why did Nokia not include a micro SD card slot on the Icon like they did on the 1520?
