I have been using Nexus 4 for a while and I am quite happy with it. Nexus 5 and Nexus 6 have already been announced after it, but tbh, pretty much all you will get with the two latter will be bigger screens. Also, remember that the Nexus phones immediately get all system updates, as they are Google's pure Android phones without any prior customization in place.
This said, gratz to Ikarus and Xside. I really thought you guys were an extinct breed
This one is my first smartphone too. I got it only after my dinosaur of a phone died in agony.
