I spend most of my time in the office doing takeoffs and quotes. I also deal with all of our system replacements and adds/changes/modifications and need to do site visits/on site markups of existing systems. I need to upgrade my laptop and want something that I can take on site. So 80% of my work is laptop 20% tablet. I had thought about getting the ipad app for my field portion but from what I see the ipad app has horrible reviews. The surface pro seems to be geared more 80% tablet and 20% laptop. I have been looking at Dell 2 in 1 devices as they are more laptop then tablet. If you are working in the field with BB what are you using?
