Through numerous bad experiences, I have learned that the most likely cause of laptop "failure" is the lack of updated drivers for new operating systems. As an example, I have a perfectly good Thinkpad T42 at home which runs Windows 7 just fine for my purposes except that no compatible ATI video drivers are available, and the generic drivers have flicker effects.

I recently saw an ASUS laptop which looked quite nice except that I would be beholden to them to release ATI video driver updates customized for it. And, I can't trust them to do that for more than six months.

What laptops (manufacturer/line) should I consider so that I could expect at least a couple years of frequent updates? I plan on running Windows 7 and installing whatever successor comes out.

I like Intel components (especially WiFi) because I can install their drivers directly from them, and they have a long history of providing updates for years after shipping a particular component. More generally, components from companies which are likely to update drivers frequently are good as long as I can install the component manufacturer-provided drivers without laptop-specific customization (like the ATI drivers).

Also, if a component can be replaced easily, I am less concerned. For example, Dell stopped pumping out updated drivers for one of its mini-PCI WiFi cards. The solution was to buy an Intel replacement on eBay for $12! That's fine. I can deal with that.

So, what laptops should I consider so that I'm not likely to be stuck between a rock and a hard place?
