After being a loyal Apple user for years this pure Android device Google Nexus 5 made me give it a try. I luckily got a chance to experience the Nexus 7 tablet which gave me a sense of quality interface and build of Nexus line. I use macs, I used to have iPhone 3gs, 4, 4s, and now using iPhone 5, I have tested hell lot of great Android devices out there from HTC One to Moto X and many others during my iPhone journey but the way Google want Android to be is only on Nexus 5.
I often think and believe design is very subjective, no matter how good your design is, you really cannot imagine how your design is going to be perceived by the audience unless until you execute your visualisation. Its more about the right time and right decision and your surroundings has a lot to do with it.
