Neocubes are small spherical magnets (about 5mm diameter). You buy about 256 or more for about $12, and you stick them together to make whatever you want, constrained only by geometry and the rules of magnetism.
This is some of what you can make: http://picasaweb.google.com/damox99/Neocube#
Find them on ebay with search terms like 'neocube', 'sphere' and 'magnetic'.
It was interesting to read the 'quantum physics article', but it had no cross-linking and was very much one person's view. This will matter much more for contentious articles (e.g. 'Keynesian Economics', or 'Islam'). These documents are not 'living documents' and its hard to see how they can be, without crowd sourcing.
I have a pretty good 24" lcd (a dell 2407wfp), which is big enough that I can put it about a metre away (or more) and still read pdf files (and html, which conveniently wraps when zoomed).
It means i can read without glasses, so I can have tv in the background.
This test is only on readability of a single book (quite validly, and they pretend nothing else).
Being able to access and/or transport a huge list of books easily on digital media is also good, not to mention being able to access the net for other reasons, and all without carrying around a separate device.
Given that I like to carry a laptop, and that its screen makes it HANDS FREE on a table, or at night on my doona (mouse under doona!) I will stay with the laptop.

I meant to add that being a living document is particularly important in a rapidly changing field such as the 'quantum computing'.
