I would vote for the silver -- it's easier on my eyes and less distracting when reading. And it was the only colour in stock and available to buy (I could have waited a few weeks, but I have no will power).
Having said that, however, it does tend to disappear into the background and if I didn't have the tri-fold cover (which is orange on the inside) I would be forever in danger of putting my coffee cup down on it.
