A couple days ago, I posted an article on UX Magazine about inexact design. It follows from the way I have been working for a long while, and some presentations I've given, but after reading some other work on electronics design and service availability (and talking with some other smart UX folks) I codified it a bit more.
We are currently working on creating responsive designs for a web site which provides/sells service-based products. The client wants the designs based off their desktop experience. One of the pages compares the service features in a side-by-side column format. Looks great in the desktop view but it not going to work in the smart phone view.
I am hearing from a lot of clients who are asking questions about whether or not now (or ever) is the time to invest in a responsively designed site - that is, if they should use media queries and fluid proportion-based layouts to provide an optimized experience across devices and browsers.
