PC attack vectors

Jethro Carr offers a useful guide to personal computer vulnerabilities in Attack vectors for personal computers.

For non-technical readers it’s a good primer, for more technical people it’s a nice reminder of the things you should guard against.

Carr points out these threats are insignificant compared with the computer owner’s behaviour. And as he says:

never forget the biggest weakness – beating a user with a wrench until they give up their password is a lot cheaper than developing a sophisticated exploit if someone just wants access to some existing data.

New Zealand PC market down 27 percent

Research company IDC reports New Zealand PC sales fell 27 percent in the first quarter of 2013 when compared to the same quarter a year earlier.

In a press release IDC describes this as ‘softness in PC sales’. That’s putting it mildly, we’re seeing a collapse. People are either skipping or delaying PC upgrades preferring instead to buy tablets or smartphones.

Understandably PC makers are cutting the supply of machines. This may lead in turn to less choice and difficulty getting hold of popular models.

IDC says Apple picked up market share in New Zealand during the quarter. It isn’t hard to see why, the company continues to offer more attractive computers and there’s a knock-on effect from Apple’s success with the iPhone and iPad.

In my view PC sales peaked some years ago and are unlikely to recover. There is no innovation waiting in the wings to kick-start a revival.

On the other hand, as I wrote yesterday, advances like the 12 hour battery life in Apple’s new MacBook Air will help slow the decline. I suspect traditional PCs will continue to sell for a while, just not in large numbers.

 

Underlining Apple’s stunning PC market victory

Apple's PC market victory

The thing that matters most about selling computers is making money. I was conscious of this on Monday when I wrote about Apple’s stunning PC victory.

That story says Apple’s iPad laid waste to the PC industry in the space of just three years. But what about that PC market. Who is the winner there?

The only winner is Apple.

While it is obvious Apple makes proportionally more money from selling PCs than other computer makers, I didn’t have enough information to figure out how much extra the company makes.

Horace Dediu at Asymco has the numbers and it turns out Apple’s PC market dominance is even more pronounced when you look at the slice of profit that company commands.

Apple accounts for almost half of PC industry profits and it makes more than the next five PC makers combined. A stunning victory.

And this is another reminder of why Microsoft is pushing ahead with Windows 8. It is the only plausible route out of this dead-end for Microsoft and the non-Apple PC makers.

PCs retreat as tablets surge

The journalist's ipadWe all know tablets are wiping the floor with traditional PCs, the latest numbers from IDC show tablet sales have almost caught up with desktops. That’s quite something considering the tablet market didn’t get under way until 2010. It looks like they’ll go past laptop sales in 2013.
