The co-founders behind Twitter the addictive micro-blogging service have revealed that a possibility of a paid version of the service is in the works – although they were quick not to give too much information away.

Speaking at All Things Digital conference, Evan Williams, Co-founder and CEO of Twitter explained that money will start changing hands on the website, revealing: "There will be a moment when you can fill out a form or something and give us money" and that the team behind Twitter were "working on it right

In just over a year, the BBC's iPlayer service has turned on-demand TV from a cutting edge idea used by tech enthusiasts to a daily experience for millions of people.

iPlayer is now the UK's 22nd-most popular website, second only to YouTube among video websites, and over 100million programmes have been viewed by Virgin Media customers since iPlayer launched on cable boxes last June.

You can access iPlayer through mobile phones, on the Nintendo Wii and PS3, and the next step will be Freesat receivers via their built-in Ethernet port. But every new

You don't have to wait for your favourite web sites to develop a mobile version that still has enough of the features that made the site worth visiting; you can get a real mobile browser instead.

The release version of Skyfire comes out this week for Windows Mobile and Symbian (a BlackBerry version is in private alpha) and delivers on the promise of the beta version: full web browsing with Flash, Silverlight and JavaScript that works on a mobile.

Skyfire can cope with normal web pages because it actually uses Mozilla's Gecko rendering engine on the

Google has shown off the next iteration of its Android OS - codenamed Donut - at the recent Google I/O conference.

The next version will build on the search functionality of the device (which is hardly a shock given Google's backing) and has taken the 'anything you can do, we can do better' approach to Apple's iPhone 3.0 update by bringing its own version of Spotlight.

In the next version, users will be able to search both locally on the phone and online at the same time, as well as being able to pore through calendars, music and other applications

Have you seen the demo of Spotify on Android yet?

If not, check it out and listen really carefully. That sound you can hear in the distance is Steve Jobs swearing.

It looks like Android has found its killer app.

Google's phone OS is pretty nifty, but so far it's lacked the cool factor of Apple's iPhone. Spotify, though, is cool - and if it feels free to the user, it could drive a great big truck through Apple's iTunes business and its iPhone business too.

Being able to stream music from Spotify wherever you go is immensely attractive,

By God it's a scary time to be buying a motherboard. We've gotten so comfortable with Intel's age-old LGA775 socket – which has been with us since 2005's Pentium 4, amazingly – that the bad old days of deciphering which chip would go in which board seem like a distant nightmare.

Well, prepare to start screaming and waking up in a cold sweat again, because right now there's a confluence of confusing sea-changes going on. These mean picking up a new mobo involves either sacrificing future-proofing or having to drop a small fortune on a new chip and RAM as

When a company decides to call its search engine Bing, as Microsoft has decided to do, you've got to wonder what names they rejected. Spang? Facthammer? Searchy Searchy Search McSearch?

You've also got to wonder what they were thinking of when they chose Bing, because the four things that immediately spring to mind are Yahoo, the late Bing Crosby, Chandler from Friends and the bar in the Sopranos.

Does Microsoft really want us to think of an ailing search provider, a long-dead crooner, an actor with addiction problems and a mafia strip club whenever

Cameras that will not self-destruct when seriously wet are not new, but some are better at taking a good soaking than others. The real deal, however, is a camera that will keep on working when completely submerged.

The machismo of these Commando-style cameras is measured by how deep you can take them beneath the brine. As any swimming pool diver will know, water pressure builds up fast as you head below the surface.

The Olympus µ Tough 8000 can hold its breath and keep on shooting at depths of up to 10 metres. This makes a great gadget for

As one of the only 'free' platforms, Microsoft's Virtual PC 2007 has an advantage in the value-for-money stakes, but it's also the most basic, and the one that refused to work with the two Linux distributions that we used to test the software suites.

Both Ubuntu 9.04 and the older 8.02 images crashed, so if you're looking to experiment with a wealth of OSes, look elsewhere.

Installing Windows 2000 was reassuringly straightforward, though, and we didn't have any problems updating the client with the Virtual PC tools to add network drives, better

VMware Workstation 6.5 is slick, powerful and the most fully featured of these suites, boasting USB support and DirectX 9.0c rendering.

On top of that, Unity enables you to interact with the client's apps as if they were running natively. It's also the only platform that installed all three operating systems without a hiccup.

VMware Workstation is, however, the most expensive app by some way and as such is out of the reach of most consumers. Don't be too put off by this, though, as there's a 30-day trial that could be the perfect solution when
