Just got in from watching this - an amusing yarn but the bits involving computers were a little far fetched to say the least (in fact, about as bad as anything since the computer virus written for the alien space craft in Independence Day)...
What I learn't about computers from this film:
(1) Whatever OS they use at the CIA, you can get a C++ program to run without first compiling it - oh yeah - and before you've logged in
(2) A laptop with a wireless LAN card works from several miles away.
(3) It takes 1.2 seconds to knock up a reasonable simulation of a CIA webcast application

There's a load more, but I feel a bit nerdy posting this much
