Swedish furniture maker Ikea makes a surprise Mobile World Congress 2015 appearance, where it launches a portfolio of bedside tables, lamps and desks featuring built-in Qi wireless charging.

Designed by David Wahl, the furniture promises to eliminate cable clutter by charging any smartphone with Qi wireless charging support. In addition the company also offers a standalone Qi chargers customers can integrate into current (Ikea, obviously) furniture with a spot of drilling.

Microsoft launches a more portable version of its cross-platform lightweight Universal Mobile Keyboard at Mobile World Congress 2015-- the self-descriptive Universal Foldable Keyboard.

Like the Universal Keyboard the Foldable version is compatible with all iOS, Android and Windows devices and, like the name suggests, users can fold it in half for easy stowing in bags or even jacket pockets. Magnets hold the keyboard closed once folded.

It is all of 11.5mm thick when folded, and unfolds into a full-size keyboard measuring 29 x 12cm. Users can pair it via Bluetooth with up to 2 devices, with a button handling the switching between devices.

Pebble Technology returns to Kickstarter to crowdfund and/or open preorders for its next generation smartwatch-- the Pebble Time, an update featuring a colour ePaper display, microphone and a revamped "timeline" user interface.

Like the first Pebble, the Pebble Time features four physical buttons and requires connection to a smartphone (via Bluetooth LE) for actual usability. However it replaces the monochrome ePaper display with a 64-colour version, while the stainless steel body is slimmer and slightly curved to hug the wrist better.

Battery life clocks at around 7 days, making it superior to just about every other alternative on the market.

German keyboard maker Das Keyboard announces a smaller version of the most recent typing device sharing its name-- the Das Keyboard 4C, an 88-key mechanical keyboard designed for customers wanting more desk space.

Like all other Das Keyboard offerings, the 4C features mechanical key switches for tactile and audio feedback-- or, as the company puts it, "tactile feel" and a "psycho-acoustic experience." It features a "tenkeyless" design lacking a numpad, if still complete with media and special function keys, dedicated Windows key disable control and built-in n-key rollover (NKRO) over USB support. Connectivity comes through USB 2.0.
