Here's the five stories from PC Advisor this week that generated the most comments from our readers

Windows Phone 7 Mango: First Look at the hot new features

This week, Microsoft took the wraps off 'Mango,' an update to its Windows Phone 7 platform that includes more than 500 new features designed to improve multitasking, offer more dynamic information and make apps and the OS work together more efficiently.

James Boone was "very excited about the update and the new hardware to ship with it".

"There are a few features that I haven't seen mentioned that I'd like to see though," he said.

Microsoft online chief: I would never log into a Chromebook

Google's love of inside jokes was on display this month at the Google I/O conference, where a demo of Google's new 'Chromebook' computers used the login name 'Tom Rizzo'. Rizzo is the senior director of online services at Microsoft who has claimed that Google is "failing" in the enterprise. When told about the demo, Rizzo said Google can keep using his name in demos because "me logging into a Chromebook will never be a reality."

Francis Bookshire said: "I trust my information with Google more than I do with Microsoft, but then again I wouldn't save confidential information on Google's servers either."

"I do use Gmail though, much better and cleaner than that Hotmail rubbish that M$ offers," she added.

UK firms get one year to comply with cookie law

The Information Commissioner's Office is giving UK firms one year to comply with EU legislation regarding cookies. Changes to the EU Privacy and Electronic Communications Directive came into force this week and require websites to gain consent from web users to store or access information on their computers, under changes to European law. However he Information Commissioner Christopher Graham, who is responsible for enforcing the legislation, has agreed to give UK businesses more time to implement the necessary changes.
However Samuel Shoesmith was not impressed with the changes at all.

"Yeah, protection, protection and all that. I do really look forward to the days when I get pop-ups on every website listing what they are going to store about me therefore hindering my work. If web laws need to be changed it should be up to the individual country not the EU!" he said.

How to speed up your PC: 24 performance tweaks

We looked at hardware upgrades, software tweaks and networking tricks that will give your PC a definitive boost of power. But John_696969 disgareed with one of the tips.

"There is absolutely NO POINT in moving from 4Gb to 8Gb unless your running a 64bit system and operating system. So the Dell item is pointless unless we are told it was a 64bit system," he said.

"It does not surprise me that there was no performance change if it was a 32bit system as anything above approx 3.8G RAM is un-addressable."

Hold the half-baked hardware

And finally, we questioned how much should you pay for a laptop compared to how much you actually want to fork out. While the latter is probably a lot less than the figure you mentally answered for how much you should pay but the correlation between the two is important. It's often true that you get what you pay for, but it's also the case that you get what trends dictate is available, at a price the market will bear.

But as Mickey pointed out: "And what exactly are we going to do if we don't want to wait until makers get them right? We're hardly going to start our own company to do it ourselves. We'll buy it anyway."
