When you are handed a completely different and new shiny object at the office, you might feel elated at first (especially if the equipment is better than your own), but you also know you're going to face a frustrating learning curve that will, at a minimum, slow you down while you figure out the nuances. I heard a lot of friends howling and complaining about being forced from the comfort of Microsoft® Windows 7® into the unfamiliar territory of Windows 8®. Think back to the years before you had a preferred mobile operating system. Before you became an iOS devotee, or perhaps an Android™ zealot. Do you remember how frustrating the learning curve was when you acquired a new phone? It doesn't matter if it is a massive upgrade - it's a new massive upgrade, and new nearly always means disruptive.
