Distinctive Marks
The classes above are not rigid; there are "edge devices" in most of them. For instance, the "subnotebook" category can usually be distinguished from the "PDA" category because a subnotebook has a keyboard and a PDA has not; however, tablet PCs may be larger than subnotebooks (making it seemingly correct to classify them as laptops) and also lack a keyboard, while devices such as the Handspring Treo 600 have something that might charitably be called a keyboard, but are still definitely in the "smartphone" category.
In the higher end of the spectrum, this informal rule might help:
- You can throw a laptop
- You can lift a workstation
- You can tilt a minicomputer
- You cannot move a mainframe

Famous quotes containing the words distinctive and/or marks:
“Fortunately, the time has long passed when people liked to regard the United States as some kind of melting pot, taking men and women from every part of the world and converting them into standardized, homogenized Americans. We are, I think, much more mature and wise today. Just as we welcome a world of diversity, so we glory in an America of diversity—an America all the richer for the many different and distinctive strands of which it is woven.”
—Hubert H. Humphrey (1911–1978)
“I regard almost all quarrels of princes on the same footing, and I see nothing that marks man’s unreason so positively as war. Indeed, what folly to kill one another for interests often imaginary, and always for the pleasure of persons who do not think themselves even obliged to those who sacrifice themselves for them!”
—Mary Wortley, Lady Montagu (1689–1762)
