It’s always interesting to see how technology products from a few decades ago stack up against the ones available now.

Alfred Poor and David Foster of Input Output created and designed an infographic that compares a 30 year old IBM PC with the iPhone 4.

It’s just amazing to see how clock speeds, memory sizes, battery capacity and screen resolutions have increased over the years, while at the same time shrinking in size so as to fit in a device that you can carry in your pocket.

So the next time someone tells you that he or she isn’t happy with their iPhone, point them to this link to remind them of how far technology has come.
