I finished rereading 2001 and 2010 A Space Odyssey after many years on my Nook. I guess it's appropriate to read it on an ereader. I always enjoy Clarke's optimistic view of the future. There are no true villains. The characters struggle, but reason through problems. It doesn't mean they will be happy, just that they will do the best that they can.
I did prefer 2010 the book over the movie. The movie introduced a silly USA vs USSR controversey at one point, where the two crews separate. It was never very believable. Here the unknown schemes of the advanced beings bring the true unknown mystery.
I like how HAL was redeemed in 2010. It was fitting that Bowman chose him to accompany him before the Discovery was burned up.
