I'm writing copy for a new web application and I'm having some trouble with it.
On one headline I've written "It's dead simple ...", but while my client was reviewing it he asked if this is not too 'cool', and suggested "It's really simple ...".
The context is: Web 2.0 application, really COOL with a beautiful bright homepage design!
How can I convince him to use "Dead simple...", or am I wrong and "Really simple..." is better?
