Hm, that's two resizes in the case of images - first time you resize down from 
the original image to the thumbnail-specified size, and then you resize 
*again* from the thumbnail-specified size to the displayed size.
I can see three clear disadvantages with that approach:

- Unnecessary performance (= battery) issues, obviously
- Resizing from a small, already-resized image looks just terrible
- Plus you can't really do plaintext previews with tiny fonts (like present
  in Konqueror for KDE 3) because you must assume that resizing the
  thumbnail makes it unreadable.

That imho defeats all quality requirements that can be demanded from a 
thumbnailer (bad image quality, unreadable text) unless you use the exact 
specified sizes. There must be a better way to do that, no?

Hoping for the best,
