I do know quite a few people that don't want to, or have no interest in taking the time to find out what the iPad can really do. Some are intimidated at the thought of using a new operating system, some are happy with what they have always used and just don't want to learn a new OS, and some are just perfectly fine with the iPad being their media consumption device. These are all ok, but it doesn't change the fact that the iPad is a very capable device that can and has replaced a laptop for a large minority of people. I myself am pretty excited, happy, and proud of the fact that at 61 years old, I learned a new OS on a device that has replaced my need for a traditional laptop.
Now, all that being said, it is true that not everyone can realistically replace their laptop with an iPad. My wife is an electronic engineer and at its level of evolution the iPad is in no way advanced enough to replace a full desktop OS for the work she does. It is reasonable to accept that the iPad cannot be everyone's primary computer, just as it is reasonable to accept that it can replace a traditional computer for many people. I am fortunate that my Real Estate and property management work are easy for the iPad to handle, and will only get better as the OS evolves. I do stuff like (create, fill, and sign contracts), create and edit documents, (create, edit, and annotate pdf's), hand written notes, file management, time management, emails, texts, client communication, sketching house dimensions, taking house pictures, and occasionally reading some news, playing a game, or watching YouTube while waiting for a client.

@XIO[-]OIX the iPad easily replaces a laptop for me and even makes using a computer for work and personal life fun again. Unfortunately a lot of people will never bother to take the time to find this out, who potentially could.
