From home interiors to kitchenware, from automobile designs to graffiti styles, it seems that retro is making a comeback for good and in this case it has carved a new niche for itself in the world of digital calculators. Hewlett Packard recently released a series of three vintage calculators as applications for the apple iphone and copying the HP 12c, HP 12c platinum and HP 15c on the exterior, the new calculators should be a delight to anyone who still loves to get stuck in the 80’s. The design is so retro that barring the HP logo, you would thing this is an old and useless dump.

While the original applications are preserved, when the phone is turned in vertical mode the calculator condenses into a smaller version of the designs and makes its jump into the digital mode on touch of the HP logo. Cool, useful and trendy, the retro design along with iphone adaptability makes it a decent buy indeed!
