many of you will quote enjoy this.

"Once upon a time, in a kingdom not far from here, a king summoned two of his 
advisors for a test. He showed them both a shiny metal box with two slots in 
the 
top, a control knob, and a lever. "What do you think this is?"

One advisor, an engineer, answered first. "It is a toaster," he said. The king 
asked, "How would you design an embedded computer for it?" The engineer 
replied, 
"Using a four-bit microcontroller, I would write a simple program that reads 
the 
darkness knob and quantizes its position to one of 16 shades of darkness, from 
snow white to coal black. The program would use that darkness level as the 
index 
to a 16-element table of initial timer values. Then it would turn on the 
heating 
elements and start the timer with the initial value selected from the table. At 
the end of the time delay, it would turn off the heat and pop up the toast. 
Come 
back next week, and I'll show you a working prototype."

The second advisor, a computer scientist, immediately recognized the danger of 
such short-sighted thinking. He said, "Toasters don't just turn bread into 
toast, they are also used to warm frozen waffles. What you see before you is 
really a breakfast food cooker. As the subjects of your kingdom become more 
sophisticated, they will demand more capabilities. They will need a breakfast 
food cooker that can also cook sausage, fry bacon, and make scrambled eggs. A 
toaster that only makes toast will soon be obsolete. If we don't look to the 
future, we will have to completely redesign the toaster in just a few years."

it continues from there. go read it.
