HopTo has been hard at work solving what it feels are the three basic productivity problems while working on an iPad: file storage, interoperability and multitasking. Of course, not everyone has a tablet to begin with, so hopTo has risen to the occasion in order to solve a fourth by hooking up one lucky Engadget reader with a brand new iPad Air. The free app just landed in the App store this month and it's worth a look, offering convenient access to cloud storage providers, Microsoft Office file editing and even remote access to your computer, all straight from your slate. Having an iPad Air with all that on board could definitely help take some weight off your shoulders in more ways than one. So it seems the only problem left to solve is whether to enter one time or maybe four (down at the Rafflecopter widget below). Do ya feel lucky? Well do ya?
