My laptop is a great tool for my job.
I use it for a lot of technical issues, principally for modelling and designing system applications.
I use my machine for meeting when I need take notes and make presentations.
In my laptop there are many special folders where I keep important projects information, such as schedules, commercial proposals, contracts, technical documentations, templates, etc.
My emails and web contacts are saved in my laptop also.
Well, if my computer dies, I will die with it too…
