Yes I do. But not solely. I have a Desktop PC in office and one at home, while iPad is my mobile computer and I use to deliver lectures and ppt presentations. I use it for searching references, downloading papers, create and edit word documents such as reports, manuscripts, question papers etc. My iPad doesn’t have a good chemistry drawing program and that is a drawback and another grief is not having an app like Origin Pro software for graphs, spectra, charts etc. I have purchased iPad Pro, which is yet to be received.
