Bill Moggridge, who designed the first laptop, the GRiD Compass, in 1979, calls this Mac "the nearest to the ultimate laptop that has been achieved to date, for its huge and delicious display as well as for its elegant and refined appearance and proportions."

More design articles: Take an inside look at the making of the Ocean, a new phone from a company called Helio (see "Soul of a New Machine"). Take a decidedly non-inside look at how Apple approaches design (see "Different"), and read a review of how Apple remains deeply committed to being a computer company (see "The 'New' Apple"). Get insights on the state of Web design from print-design legend Roger Black (see "Help Me Redesign the Web"), and find out what Bill Moggridge, a cofounder of Ideo and designer of the GRiD Compass, thinks makes good design (see Q&A). Finally, hear from Technology Review's Editor in Chief, Jason Pontin, on the well-designed technologies that are "beautiful machines" in this video.
Voltage is the difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts. It measures the potential energy of an electric field to cause an electric current in an electrical conductor.
Most measurement devices can measure voltage. Two common voltage measurements are direct current (DC) and alternating current (AC).
Learn the fundamentals of creating an AC or DC voltage measurement system. See how to properly connect the signals to your data acquisition system for accurate acquisition.
