Why Consumer Products are “Designed to Fail”

Why Consumer Products are “Designed to Fail”

Either the marketing team or the designers wanted it that way, right?

Managing Technology Overload

Managing Technology Overload

Manufacturers are racing to tie every electronic device we own together into a network of incessant information, which has resulted in some beautiful connected devices, but there's a fine line between not enough information and far, far too much of it.
