This article really loves that dock, but I've heard mixed things about it on reddit (/r/nexus4). In particular, the phone slides off when it gets dusty, because the dock is NOT in fact magnetic (as the article mentions). You can tell (apparently) because if you put a piece of paper behind the phone, it isn't held up at all. The phone is completely held up by the rubber rings on wireless charger. I don't have the wireless charger though, it's a bit expensive for me; maybe someone else here on Hackernews has some more concrete opinions?
