A virtual keyboard
The Cube Laser Virtual Keyboard shows us a glimpse of how our future keyboards has evolved -- from hardware to touchscreen -- and now projection.
The keyboard has a full QWERTY layout which is projected across any flat surface, together with a "mouse mode" which lets you use your finger when typing. It is connected wirelessly to most laptops and many mobile devices, including the iPhone and iPad, and charges via USB. At the moment, the rechargeable battery is able to last for 150 minutes.

LG Pocket Photo PD221 Mini Mobile Printer for Android
People often rely on their smartphones to take pictures -- especially if more sophisticated DSLR kits are out of reach. If you happen to be an Instagram-happy student, you might want to do more than upload your snaps to Facebook -- and this is where LG's mini mobile printer comes in.
If you have an Android-based smartphone, connect the printer via Bluetooth or USB to edit, upload and print your images.
WD My Passport 1TB portable external hard drive
An external hard drive is a sensible way to make sure that if your computer fails, you won't lose that essay you've (apparently) been working on for months, or the dissertation which is due tomorrow.
While there are many on the market, I particularly like WD's My Passport drives. Available in models with 320GB to 1.5TBs' worth of space, the drives can be password protected, are portable due to their small and compact designs, and can be set to automatically back up software.
