First this week, Facebook is adding video chat to its service. The new feature was developed with Skype and works through a browser plugin on Firefox, Internet Explorer, Safari and Chrome on Windows and Macintosh computers.

Philip Su, Facebook: "You connect on Facebook to any one of your friends by using a chat tab or viewing their profile page. It's a simple one-button click on the call button and all of a sudden you're connected with your friend through video."

For now, video chat is only for one-on-one conversations, but it could be opened up to larger groups in the future.

Launch of the new service comes days after Google began rolling out its Google Plus service, which includes group video chat.

To get started on Facebook, visit facebook.com/videocalling to download the plugin. Facebook said the new video service is the first of many new applications to come in the next couple of months.

The cost of roaming could be getting drastically cheaper for European consumers from 2014. The European Commission this week published a proposal that would allow customers to sign up for a second carrier that would offer cheaper mobile roaming. Consumers would be able to keep the same phone number as their regular national contract.

Neelie Kroes:  "We are proposing a long-term structural solution to get to the root cause of roaming rip-offs, namely the lack of competition. By giving mobile users more choice, and by making it easier for alternative operators to gain access to the roaming market. For voice, for text, and for data."

The European Commission wants the difference between national and European roaming tariffs to almost dissappear by 2015, and sees the proposal as a way to reach that goal.

Neelie Kroes: "We are proposing that by July 2014, retail caps before VAT would reach: 50 cents per megabyte of data, 24 cents per minute for a call made, 10 cents per minute for calls received and 10 cents for a text."

Boeing's 787, its newest passenger airliner, arrived in Japan this week for readiness tests ahead of its entry into commercial service. The 787 is not only the newest airliner in the skies, but it's also the most high-tech.

The biggest changes come in the fuselage, which is made of a composite plastic, not aluminium like other aircraft, and that means it's lighter.

There have been changes to the engine housings, with a noise-reducing material around the air intake and tipped exhaust covers to make life quieter for passengers and those on the ground.

Inside, the 787 has an all electronic cockpit and aircraft wide computer network that links the flight deck to all the control systems.

Sensors throughout the aircraft constantly measure flight parameters and, if sent back to base, allow real-time ground-based monitoring to take place.

For passengers, the most obvious differences will be in the cabin. Pull-up and down window shades are gone in favor of electro-chromatic dimmable windows. They act like adjustable sunglasses and should put a stop to the glare often encountered when flying high above clouds.

On ANA, high-tech Japanese "washlet" toilets are fitted in all classes and passengers will also find a power outlet, USB port and iPod connector and the entertainment system screens are touchpanels.

The 787 will enter service on domestic routes in Japan during August or September.

Many people dislike PowerPoint but few would take a political stand over it. However, that's exactly what Switzerland's Anti-PowerPoint Party (APPP) seeks to do.

Founded by Matthias Poehm, the group claims Powerpoint and similar presentation software cost the Swiss economy 2.1 billion Swiss francs (US$2.5 billion) annually. Across Europe they say that figure balloons to US$160 billion.

Under Swiss law, a national referendum can be called on almost any subject if the signatures of 100,000 voters are obtained, and that's what the party is trying to do. The vote would ban the use of PowerPoint and other presentation software in presentations throughout Switzerland. It also plans to present candidates for national elections in October.
