At my work I get a new laptop every 15 months!! do I need a new laptop every 15 months ... absolutely not.
Well it really depends on what you are doing with it. If you are into multimedia development kind of stuff, even the state-of-the-art-laptops are not powerful enough for that.
There is a paradigm shift, now laptops are being used as servers as well. And then the trend for virtualization, that all needs more and more resources.
And then the newer laptops are less energy hungry, have more embedded security related features and so on.
