Yes. Well, thanks very much, Nick. I think this is not an abnormal guidance that we see. Look, we had very, very strong performance in mobile devices this year. We came into the year with an expectation of the market being flat. I will tell you, I mean, we didn't give guidance at the time, but had you asked me at the end of Q1, what would mobile devices be for the year? I probably would have thought it would be even down given the disruptions that we saw in the first quarter to our China facilities. And the vast majority, if not all, of our mobile device production is really in China and all of those factories were shut down, as you know, for the better part of three weeks, due to the early stage of the coronavirus. And then our team just did an unbelievable job of reacting to the strength in the market. And the strength this year, well, there was, on a sequential basis in the fourth quarter, strength in smartphones, where we really saw a lot of strength this year, was maybe not surprisingly in devices that are needed by people when they are working, when they're learning, when they're being entertained at home. So, things like laptops; things like tablets; we saw a lot of strength in wearables, I know, a lot of people got on health kicks and maybe these wearables can be very useful there; a lot of strength in things that go in your ears, hearable devices as we call them, and probably because you have a lot of people doing work and school from home and they might have other people in the same house and they want to have some privacy. Whatever the reason is, there was just a great amount of strength and our team was able to react to quite unexpected demand. And so, as you go into the first quarter, I think that we would expect normally some relaxation of that demand. I mean, look, anecdotally, I tried to buy Christmas presents for my wife and my daughter of a computer, because they both have really old computers and I totally failed as a father and a husband and they each got their present, one got it about a month late, and the other one still hasn't gotten hers. So, there was a real demand back in the fourth quarter, in particular for these devices. And I think we wouldn't expect such a continuation here in the first quarter.
