Click Online's regular feedback slot allows you to have your say on issues mentioned in the programme and other technology matters.

This week we answer some of the questions you sent us on new computer operating systems.

Anyone looking at our inbox over the last weeks would know that something had happened.

Was it a virus, was it a denial of service attack?

No. We looked at the new Mac Operating System, then we covered the new 64-Bit version of Windows XP, and then we gave you a preview of Microsoft's up and coming operating system Longhorn.

I should say that most people were very unimpressed at the transparent windows:

"You say that Apple and Microsoft both 'announced' 64-Bit operating systems.

No. Apple released it, Microsoft chose this moment to 'announce' and 'preview' their system."
Jim Hassinger, Glendale, California, USA

"Apple shipped its update. Microsoft showed pictures. It's different, not 'both have announced'."
Brad Schrick, Palo Alto, USA

This confusion is caused by a rather odd decision by Microsoft.

Both Microsoft and Apple launched their software and made it available in the same week, but currently Microsoft are not selling 64-Bit Windows in the shops.

At the moment it is only being made available to computer manufacturers, so if you want a copy of 64-Bit Windows right away you will need to buy a PC as well, which seems a strange way of doing it.

But the pictures we showed was a preview of Longhorn and we will not see that for a while.

Stephen also said:

"Desktop PCs have had to wait quite a long time to move to 64-Bit operating Systems." And got this response:

"Not so. 64-Bit hardware has been in the desktop arena for at least a year and Linux has been there to run it. Just because Microsoft are late to the party does not imply the party hasn't started yet."
J Pelan

Indeed, the AMD 64 chip was launched in September 2003, and Linux can run using it.

Absolutely true. Good point, well made.

I am not sure you will like Stephen's answer:

"I believe that it still isn't time to call Linux a 'desktop' operating system. It simply isn't as usable for everyone as Windows and OS X are.

"It will be soon, but, for the time being at least, Click Online doesn't think it is."

We will be taking a look at Linux soon and we will be sure to look at the 64-Bit distributions.

Now an email about 64-Bit processing from Dave Duke, who rather modestly calls himself "one of the UK's foremost experts in IT security":

"We have worked out, on average, 98% of applications use less than 5% of a computer's CPU.

Microsoft Word on our average PC takes around 3 seconds to load. Is it really worth me spending hundreds, or even thousands of pounds on hardware and software to make it load in 2 seconds?"

We totally agree with you Dave, people should not feel that they need to upgrade at all.

We think we should hold off from buying the latest kit for as long as possible, unless it is really needed, because it only ever gets cheaper.

"I enjoyed watching the Mac OS release. I really wonder if Tiger OS release will woo PC users to the Mac. I think people will move on to Linux in the future when Linux really becomes user-friendly."
Kabeer Ahmed, Bangalore, India

We think the move to Linux is distinctly possible, simply because there are so many more PC systems out there than Macintosh. What do you think?
