Many might not think about it, but Bluetooth wireless communication has increasingly become part of our everyday lives.

It’s used to link mobile phones with hands-free headsets, it’s used to transfer files, it’s an essential part of connecting controllers to games consoles and peripherals to computers and tablets, and that’s just the start.

But what is it? How does it work? And why is it called Bluetooth?

The last question has a relatively simple answer. Bluetooth is the anglicised name of Harald Bl

The Samsung Galaxy Tab 2 has been announced ahead of MWC 2012, with the Korean firm rebooting the chassis of its first tablet.

The new tablet features a 7-inch screen to cater for the smaller tablet lover, but more importantly is running on Ice Cream Sandwich (or Android 4.0) and may well be the first from the company to bring the next generation platform.

The rest of the technical specs are less exciting: we’re looking at a 1GHz dual core processor running under the hood, with a 3MP camera on the rear.

Samsung has overlaid the Ice Cream Sandwich platform with its own TouchWiz UI too, and video calling will be supported through a VGA front-facing sensor.

Fuzzless front

The screen might not be too shabby it seems, as while it’s ‘only’ LCD (rather than the fancy-pants Super AMOLED offerings from the Korean firm) the resolution of 1280×600 should be enough to keep users complaining of fuzzy displays.

Other key specs that don’t seem to have moved things on much in a year and a half include: 1GB of RAM and the choice of up to 32GB internal memory.

Intriguingly, Samsung is referring to the device as the Galaxy Tab 2 (7.0) in its press materials, so it seems likely we’ll be getting larger variants of the same device in the same way as the Motorola Xoom 2 has been offered.

Thomas Richter, Samsung’s director of portfolio management, told TechRadar: “Since 2010 we have been bringing the Galaxy Tab range. In 2012, we believe that people want to experience more on the go.”

The Samsung Galaxy Tab 2 UK release date has been set for March, so expect to see our full review up any time soon.

You remember that story by that Scandinavian dude? The one where the world is made of crepes and silver monkeys would ride unicorns across the globe in an allegory about something or other?

No, neither do we. It’s possibly made up, the flashbacks from a weekend in Thailand, or a dream. Either way, there are more important things to be talking about, like the fact Google is looking to bust Android out of its mobile phone prison (oh, and tablets. And home entertainment systems. And fridges. And… oh, FINE. It’s not confined at all).

But we are excited about anything that a) is from the future and b) can make us more like a Terminator, and a project Google’s working on with Oakley to put a heads up display in one lens of its sunglasses.

The word is these little wonders would essentially have a single core processor and around 8GB of storage, plus allow you to take pictures with a front facing camera which, let’s be honest, would make you the coolest spy kid in TechSchool and would in no way get you punched in the face and have your ultra-expensive specs stolen.

Or you can wear them snowboarding or something. Whatever, we’re not your Mum. Do what you want.

More worrying is the notion you can navigate through the menu by wobbling your head – a particularly vibrant session with Girls Aloud’s Sexy No! No! No! could have us accidentally wandering onto a lewd website or two. Well, that’s our story and we’re sticking to it.

Let’s face it – anything that stops us looking like this will be a boon.

I just called to say hello…

You’ve got to give it to Nokia – the company has realised that its user base is dwindling so rapidly that nobody will be using a Finnish phone to call at all in the future, and has come up with a clever solution.

Screw talking or texting – soon you’ll be able to share a greeting by tapping phones together and walking on quietly… conjuring up some frankly terrifying images of a bald, fat man coming up to us, tapping our phone then walking away, only for us to read ‘I live in your phone now, and we are married. Oh, and buy milk.’.

There’s a strong chance this is all a made up prank, given that Nokia is saying it’s fed up with noise pollution and it will speed up its engineer’s days by 175% or some other odd stat – but then again, this is the same Nokia that thought this was a good idea. We don’t know how to react any more.

iPad? BB10? MMMMMMmmmm…. Nice

Ever wanted to spend a minute or so being whisked around the sights and sites of London while being simultaneously blasted with info on forthcoming operating systems and gadgets?

OK, but have you ever wanted to do it with some funky techno-jazz in the background and a frankly laughable attempt by a presenter to pretend he’s in a house? WELL! Have we got (two) treats for you:

Amazon will launch a 9-inch Amazon Kindle Fire tablet, as well as a refreshed 7-inch model by the middle of this year, according to one analyst’s forecast.

Chad Bartley of Pacific Crest has increased his Kindle Fire 2012 sales estimate from 12 million units to 14.9 miilion units, partly due to the expected new models.

“We are raising our 2012 sales forecasts to 14.9 million from 12.7 million,” he wrote in a note to investors.

“But we believe there is an upward bias, particularly from the new 7 and 9-inch models, which we expect to launch in mid-2012.”

Let the real rivalry commence

A 9-inch Kindle Fire model would perhaps allow Amazon to take on larger tablets like the iPad, having already cornered the mid-sized market with its exceptionally-good-value, $199, 7-inch Android offering.

Despite selling an estimated six million Kindle Fire tablets during the holiday season alone, it is not seen as cutting into Apple’s slice of the action as the company announced record iPad sales for the three months leading up to Christmas.

A 9-inch model, probably priced around $250, would give perhaps tablet buyers a little more food for thought before splurging on an iPad 3, which is expected to launch in about a month’s time.

A new-and-improved 7-inch version of the Android tablet is likely to include many of the features Amazon left out first time around in order to get the first device out for Christmas.
