I have both desktop and laptop pcs for work. I rarely ever use the laptop outside the plant - but nice to have if I need to travel or check on something from home. I store my data on the network so that I don't have to worry about synchronizing anything. The laptop is used more frequently to present in meetings, but it did come in handy to investigate an issue over the weekend. What was originally reported as an isolated problem turned out to be plant-wide and knowing that made the difference in coming in to resolve it Saturday vs. leaving it for a Monday morning emergency.
