Why get a laptop with a nice high-resolution screen and then make it scale up the image? It seems like a waste of a very nice screen.
Rather than scaling the resolution, you could just change Windows' DPI settings. In the display properties window, and then click on "Make text and other items larger or smaller". From there, you can scale up to 125% or 150% of the normal size. This will render fonts and windows at a larger size, without blurring the screen the way decreasing the resolution does.
Once Windows 8.1 is released this fall, you'll get even better high-DPI display support. This is one of the major changes that is coming in Windows 8.1, and should make support for large text on a high-res display much simpler.
