Microsoft’s Windows operating system has been frustrating and delighting computer users in almost equal measure since it was first debuted by the software giant first in 1985. Fast forward through nearly a quarter of a century of powering the majority of the world’s personal computers, and Windows is about to hit another milestone.

Windows 7 launches on October 22, worldwide, and it’s safe to say that, as a firm, Microsoft will be collectively crossing fingers and toes that shoppers flock to the new version.

The successor to its Windows Vista operating system, Windows 7 promises to be faster, more reliable and make computing simpler than ever – so much so that like a proud parent, Microsoft hosting worldwide coming-of-age parties to help launch Windows 7 onto PC desktops worldwide.

Yet the key question is whether consumers, already stung by what many found a problematic Windows Vista, are as willing to take a punt on this latest version.

Certainly, it’s chalking up record sales – and Windows 7 has overtaken Harry Potter and the Deathly Hallows to become the biggest grossing pre-order on Amazon.co.uk of all time, and the online store says demand for the new operating system remains strong.

So why are shoppers pre-ordering in droves? Partly, it’s because Microsoft fumbled the ball with Windows Vista, leaving some users frustrated and fed-up with an operating system that felt sluggish and crash prone. A chance to jump to a shinier ship is welcomed. Partly, last time lots of people stayed away from the Windows Vista party following negative reports, remaining with the perfectly functional Windows XP instead.

The surge in sales tells only part of the story, however. Which? has talked with shoppers who tell us they are confused by Microsoft’s different versions (with six different prices at the last count), and there are lots of questions around whether the upgrade really is worth the hassle.

Certainly, a lot of the features seem fairly cosmetic on the surface, and some will appeal to only a handful of users. If you’re one of the chosen few to own a touchscreen PC and monitor, then the new multi-touch features in Windows 7 will have you clapping (and pinching and swiping) your hands with glee as your monitor turns into the equivalent of an outsized Apple iPhone.

Other features – such as easier home networking and interface tweaks to make navigation simplier are all good, but seem slight. Rather, Microsoft has been significantly reworking the technology that happens under the hood of Windows, making it less crash prone, faster, and hopefully a better experience.

If you’re happily using Windows Vista, though, then there really isn’t a compelling reason to upgrade as the new features are hardly lengthy.

And if you’re using Windows XP, then Microsoft has a different message for you: your PC is unlikely to run Windows 7 well, and you’ll have to fork out for a new computer. That’s an expense in these economic times that many consumers might find a little tough to swallow.

And, finally, amidst all Windows shopping it’s easy to forget that most new operating system launches are hit with bugs, glitches and incompatible software. That’s normal, but not any less frustrating.

So, if you are looking longingly through the Microsoft-shaped window, our advice is clear. Resist the temptation to upgrade straight off the starting blocks and wait for Microsoft and other software makers to find and fix the niggles and bugs, then feel free to jump in to Windows 7.

Go on. Admit it. You didn’t see it coming, did you? You never thought a member of the G20 nations would dare to break ranks and raise interest rates this soon.

But Australia has done just that. The Central Bank of Australia has increased the cost of borrowing by 0.25 percent to 3.25 percent. It is doing what it thinks is right for the country regardless of what the rest may think. Now, Asian countries, keen to avert another bubble, may follow Australia’s lead and ratchet up interest rates before long.

Of course, Australia’s economy is vastly different to the UK’s. It has huge deposits of iron, aluminium and nickel that are in demand by mineral-hungry China. That said, Australia did briefly flirt with a downturn, which it successfully corrected with 21 billion pounds of fiscal stimulus.

But the UK is not Australia. We do not have huge deposits of mineral, and we are not near fasting-growing Asian countries either. What we do have are consumers saddled with over a trillion pounds of debt following a decade of binge borrowing, and a national debt burden of similar magnitude.
Therefore, it is unlikely that we will experience demand-led inflation. In fact, consumers are saving more of their household income than they have done for eight years.

The most recent Office for National Statistics report shows that between March and June British households saved 5.60 pounds out of every 100 pounds of household income. That is very different from the first three months of 2008 when we not only failed to save any money, but we even borrowed 50 pence for every 100 pounds of household income.

That said, we are still some way off getting our overstretched household finances back on an even keel. So, the savings ratio could go higher. In fact, it is still some way short of the long-run savings-ratio average of 8 percent of household income.

And herein lies the problem for the Bank of England.

According to the paradox of thrift, high levels of savings in a recession can prolong the economic downturn. That is because two-thirds of economic growth comes from consumer spending. So the less we spend, the longer it will take the UK economy to recover from the slump.
So what is the Monetary Policy Committee to do?

It has already slashed interest rates to historic lows. But that has failed to stimulate consumer spending. It has pumped 158 billion pounds of fresh money into the coffers of lenders through quantitative easing. But the money has, as yet, failed to invigorate the ailing economy.

However, both those measures will, in time, achieve their goals. The risk is not whether they will work, but instead, whether they will work too well and stoke inflation. Just as no one expected Australia to hike rates this soon, our days of enjoying low interest rates may end just as abruptly, and without warning. So save and invest what you can now.

Political leaders gathered in Dublin to debate both sides of the controversial Lisbon Treaty and the implications it could have on the future of Europe.

The panel consisted of Micheál Martin, Ireland's Minister of Foreign Affairs, Nigel Farage MEP, leader of UKIP, Mary-Lou McDonald, Deputy President of Sinn Fein and David Begg, General Secretary of the Irish Congress of Trade Unions.
