Standard cooktops have heating components in close proximity to electronic components, which requires a good insulation layer between them. The result is a compact but thick product. Roll-up, on the other, hand separates the two components rendering the heating component very thin and elegant. In addition, when induction coils are made smaller, as is the case with the Roll-Up, the heating component can be folded. Electronic component is placed in a fancy looking hard-drive like case.
