BBC NEWS | Technology | New Zunes to take on Apple's iPod

In general I think WiFi should not be extolled or installed on battery powered devices! I've watch several PDAs and an XDA Orbit's battery meter go from 100% to 65%, within 10 minutes of WiFi being turned on and used.

It is dangerous to have WiFi available on mobile phones for this reason alone. The regular user may sit there scanning for a hotspot totally unaware of the power being quickly drained from the device. What use is a mobile phone or PDA if it has no power, just to have the latest U-Tube clip or MP3 file. Think about it. Once you have the media how long will you be able to view/listen to it for?

The same goes for iPod and Zunes (what a ridiculous name!). Firstly if you can find a hotspot to connect too you may be using it illegally. Secondly there is the battery power drain. Thirdly, how many people actually walk with the power adaptor, when you are just out and about?

All in one devices have never been a winner with me. A mobile phone should just be a mobile phone possibly with a camera too. When you start adding blue tooth, WiFi, Media players and games its just a matter of time before the headlines appear "x found dead, no power in mobile phone to dial emergency services!"

So here are my 4 tips for WiFi...

1. Do not use it if you do not walk with the adapter
2. Ensure you are close to a power supply (e.g. GNER and Virgin trains, hotels, etc)
3. Don't assume you can use a hotspot if its open
4. Get one one of those solar rechargeable batteries, they are cool!

A ZDNet artical (02/11/06) explained the agreement between Novell and Microsoft. Its no wonder the Open Source and FSF community are suspicious. As the artical puts it these 'foes' are indeed forming an alliance, but against what? Is the alliance to deal with the (Microsoft's) customer demands as mentioned by Brad Smith? Is it to stave off the rise of CentOS and its counter part RedHat? With the biggest software company in the world plugging your software and optimising it to run on their software then which other linux vendor is getting squeezed?

So Hugo Chavez thinks GW Bush is the devil.Well with the attempted coup that the CIA bungled, because Chavez refused to fall in line (see: www.venezuelasolidarity.org.uk) this is a lesson in how to increase your popularity at the expense of you boss...ahhem, cough, cough... fellow leader. Don't get me wrong Chavez has done great work in Bolivia and with Cuba but hitting someone when they are down (even if they are the bad guy) is a cheap trick (though the bad guys do it).

So the Highway's Agency has decided to commence with work on widening the M1 to 'ease' traffic congestion. The No Widening M1 Alliance has stacks of evidence to say its not a good idea and the HA's own report says in the long run the widening of the M1 will only cause more traffic. So everyone is right! Right? If two wrongs don't make a right, surely two rights must make a right? A spokes person for the business transport alliance said on camera that businesses need the M1 widening to ensure the travel routes used by delivery trucks are "effect". That thousands of jobs are at stake if this infrastructure was not updated (not using his own words of course). And there are traffic management measure (like toll charges which the transport alliance support) that can be used to control the amount of traffic ensuring that in 2021 the problem does not reoccur (and the needle runs horiztonally across the vinyl make that comic sratching noise)... Did the penny just ...
