Technofile: You may have seen YouTube.com, the online video sharing service. The site has been so successful that it has spawned 10s, nay hundreds, of copycat sites (Veoh.com, Guba.com - the list goes on and the names get weirder and weirder).

Now Blinkxx, the site more commonly known for being able to search video, is getting in on the hype.

SelfcastTV.com will do exactly what all the others do, although it also plans to offer the ability to upload video straight from a mobile phone - certainly one to remember when you're down the pub.

Who knows where it will all end, but I dare say that Blinkxx hopes it will involve something to do with money . . .

Meanwhile, MTV is also smelling the money. September sees the launch of a new kind of TV channel, programmed by, well, you.

MTV Flux is MTV Network's attempt to copy both the video sites and the MySpace-style social networking websites. The difference is that Flux will allow viewers to publish, via mobile phone and online, messages and videos to play alongside their chosen music videos. In other words, you get to programme the television channel yourself. Hold on to your hats.

• Rumours of a Microsoft iPod killer have abounded of late. Now something official has surfaced.

Microsoft's entertainment and services division has announced that "Zune" (stop sniggering at the back there) will be the brand for a family of hardware and software products which may surface in October. Or possibly not.

At any rate, being able to share music wirelessly with other Zune devices looks to be on the cards, but features such as this will have to be more than gimmicks if it is to take on Apple's 75 per cent share of the music-player market with its all-conquering iPod.

Zune will be linked into a digital music service, most likely the Urge download store launched with MTV Networks earlier on in the year in the US and planned for launch elsewhere.

There are also rumours of Zune portable games machines. Microsoft certainly has the cash to spend on a massive launch for the Zune products, but whether it can kill off the iPod and PlayStation Portable at the same time sounds a trifle over-ambitious.

• Nokia's 3G N73 and N93 handsets hit the shops soon. The former, media-oriented, mobile comes with an heavyweight 3.2 megapixel camera with Carl Zeiss optics, auto focus and the ability to upload your images to Flickr.com automatically.

Integrated stereo speakers with 3-D sound and an FM radio join with an expandible 42MB internal memory.

Along with the N73 is the N93, which has much of the same features but throws in a 3x optical zoom, support for 30 frames per second VGA video, built-in Wi-Fi and in-camera editing.

• Apple devotees rightly annoyed at the all-round uselessness (well, from where I'm sitting at least) of Apple's Mighty Mouse, will be glad to hear it is about to get a Bluetooth wireless upgrade.

However, this still leaves the confusion of the idiosyncratic scroll ball untouched.

• Look out for a new version of the popular Razr mobile phone. The new version is a slider phone, codenamed the "Motorizr", and features a two megapixel camera, Bluetooth, microSD card.

It will also come in a range of different colours.

The Razr bandwagon rolls on . . .
