James A. Landay and Todd R. Kaufmann in 1993 ("User Interface Issues in Mobile Computing"):

"A theme common to much of the past work on mobile computing devices is the desire to run similar computing environments on the mobile machines and on the user’s office workstation. Although running many of the same applications may be useful and desirable, running the same environment may be both undesirable and, for many mobile devices, impossible."

Why do I blog this? surely this quote is deja vu here for people who reads this blog, but I wanted to have a reference about this important topic.
