If you are thinking about buying a laptop, let me suggest not to ever buy an IBM.
At the company where I work, we have bought a couple of IBM thinkpads. Mine broke down after 3 weeks (display stopped working properly). We had to send it back, only to receive it back after 2.5 months (with the problem only partly resolved). Then I had to burn a CD, but it didn’t work anymore. We were thinking drivers and other problems but as it turned out, IBM removed the DVD/CD burner and replaced it silently with a simple CD-ROM player when it was back for repairs. And they refuse any responsibility.
Add to that, other collegues are now starting to get problems with their laptops as well (mainly failing CD burners), and the laptops seem ridiculously slow compared to the specs; sometimes it just plain freezes for a couple of seconds regardless of the software you’re running.
So be warned!
