Remember how Nokia used to offer removable plastic back covers in different colours for its phones? The Lumia 820 sees a return to those simpler days-- if in DIY 3D printing form. 

Customers with access to a 3D printer can get all the files and documentation required ("3D templates, case specs, recommended materials and best practices") in what Nokia calls the "3D Printing Development Kit" (3DK). 

Users without such equipment can, of course, just buy Nokia-made back covers in different colours, as well as covers offering ruggedised or wireless charging capabilities. 

Nokia first introduced customisation to its phones around 15 years ago with the Nokia 5110 (aka 5120 in America). How times change, right?

Henge Docks reveals two docking stations ideal for Apple customers at CES 2013-- the Horizontal Dock for MacBook laptops and the Gravitas Dock for iDevices.

Designed for use with either MacBook Pro or Air models, the Horizontal Dock expands laptop connectivity options to x3 external displays, x6 USB 3.0 ports, x2 audio devices, Ethernet, SD card and FireWire 800 port. It also adds further physical security through a Kensington lock.

Docking laptops involves a 4-point positioning system for properly alignmen with the device, while a simple button press takes care of undocking.

The dock weighs 2.5kg with an Apple-style solid metal chassis and should be available from Q3 2013, with a Thunderbolt version set for a Q4 release.

Meanwhile the Gravitas Dock is an all-metal device with 7.6cm diameter and 5cm height. All-metal construction makes it weigh nearly 1kg, providing stability to docked devices and single-handed undocking.

Available in either Lightning or 30-pin connector versions, the Gravitas features a USB port and audio line-out as well as 3 interchangeable inserts handling different iDevices and 3rd party cases. It should be available from Q2 2013.

Your customers might find backup batteries useful (if not essential), but even the best backups might fail in an emergency. Enter EtonC, whose BoostTurbine backup batteries come with an additional hand-powered backup.

The BoostTurbine USB batteries have a hand crank (or "hand turbine power generator") allowing users to generate extra juice. According to the company 1 minute on the hand crank produces enough power for a few text messages or a 30-second phone call.

BoostTurbine batteries come in two models-- the BoostTurbine 1000 (provides around 50% of the standard smartphone charge) and 2000 (provides a full charge). Both aluminium construction and US/microUSB ports, allowing for use with most iOS and Android devices.

With the iPhone 5 and the next generation of iDevices comes a new Apple connector-- and Bang & Olufsen takes advantage to introduce iPhone 5-compatible upgrade to the BeoPlay A8.

Thanks to an exchangeable connector module, the BeoPlay A8 not only works with the smaller Lightning iDevice connector but is also backwards-compatible with earlier modules.

Users can even remove the connector module completely should they prefer to listen to music in an entirely wireless manner through Apple AirPlay.

Mini-USB and Aux connectivity are also included.

The BeoPlay 8 is both freestanding and wall-mountable, with optimisation providing the best sound depending on location (wall, corner or freestanding).
