Please note that CommonReader has needs that are different from other people here, he does productive work unlike anyone with an iPad/tablet... productive work requires at least a notebook... this is fact as stated...
Edit as CR not clear on his own words - Quote: "Some colleagues use iPads for reading papers and documents and for receiving mails. However, the very moment productive work has to be done they are reaching for their laptops." Simple implication, productive work is done on laptops not iPads... your words... and I don't even have an iPad, just an extreme dislike of blanket statements condescending to those who disagree...
