Per Mashable, 46% of Americans Say Tablets Will Replace Laptops. I think that the study, at least as presented, is overly blunt. I would bet that it isn’t that 46% of Americans would replace their laptops with tablets but that 46% of the tasks people perform on laptops will move to tablets. Further, I suspect that another healthy chunk of laptop-linked tasks will move to small, 3G connected, mobile devices.
What will be left to laptops? Long-form content production and more serious computational tasks.
