We all remember the day when Google was caught off guard. Yes, I am talking of the day when Google’s Nexus 4 device was sold out, within hours of it going on sale. Many found their Nexus 4 backordered. Now Google Nexus is back for a second round. It is back on sale on Google’s Play store from today. We hope Google has learnt from its previous mistakes and has stocked up enough Nexus 4 devices; otherwise they might end up ruining the holidays for many.
