Let me give you some more color if I could, Patrick. I was kind of joking with the guys around here that sometimes we're off on timing, but let's be right -- let's be on the -- we could be on the wrong side of timing once in a while, but let's be on the right side of inevitability. So if you look at the opportunity for us, it's really big on inflections. That's where you make penetration. So if you look at inflections, we've talked about flash storage [ph] around FinFETs, VNAND, very positive for us because that's where we push through the windows with those tools. So if you look at etch and CVD, we're making a lot good progress, gaining a lot in memory, in particular on inflections. And in fact, if the VNAND had been a little more robust this year, we might have gained up to another 0.5 point of WFE this year. So that means it wasn't quite as robust this year, but everybody says it's coming, right? Is it '15, '16? But kind of on the right side of the inflection, right? So -- and then within the specific question you asked about etch and CVD, etch is making great progress. Look at the numbers, up a lot, up in Q1. And the other thing is if you look at -- and memory is where the revenues are, but we're making good progress in qualification at more complicated places like foundries, too. So again, going back to timing and inevitability, if you get the penetrations, get the market share, get the products right, you can also get the gross margins right over time. So you want to be on the right side of the trends, the inflections, the inevitability of these things and then grind out cost and profitability stuff, and that's what we're doing.
Patrick J. Ho - Stifel, Nicolaus & Company, Incorporated, Research Division: Great, that's really helpful. And Bob, maybe specifically for you. You've obviously made improvements on the services business front, particularly on the operating margin line. Can you give a little more color in some of the specific tactics and moves that you guys have done that have helped drive the higher operating margins in that business group?
