Take the train into central London . . . . . Westminster Abby is cool if you're a history buff . . . . . Nelson's tomb is in St. Paul's Cathedral I believe . . . . Trafalgar Square is interesting for people watching . . . . the Tate Modern is interesting . . . . the National Portrait Gallery . . . . The British Museum . . . . . Harrods in Kensington . . . . . . take a nap in Hyde Park, Regents Park . . . .

Take your PSP for those long flights . . . . . I've got one to Rome coming up as well . . . . . or just hope they've got three really good movies and you've got two really good books.

EDIT: You have to really go looking for it because its out of the way, but from the London Eye you can walk to the Imperial War Museum - about 15 minutes I think through some twisting streets - which has some fairly fascinating things, including a Buzz Bomb, trench displays, tanks, a Spitfire, etc, etc.
