With summer here it's the perfect time to take a moment in the sun to update your portfolio. With that in mind, we've selected a few useful design mock ups ranging from smartphones like the iPhone 5, Samsung Galaxy S4, HTC to iPads and corporate identity collateral. Presentation is extremely important for any design project. It helps to show the value of the product and give the context necessary to help people understand what you are trying to achieve.
