Some of the choices for a top 30 seem weird in that a bit of fake software is justified in making a laptop 'famous', and there are some glaring omissions as well.
How about the female humaniform robot Futura from the black and white movie 'Metropolis' from the 1920's, GORT from 'The Day The Earth Stood Still' (the original 1950's), or the Library computer 'Prime Radient' from Azimov's 'Foundation' series.
Still more: The Great Machine and Robby from 'Forbidden Planet', NDR-113 (Andrew) from 'Bicentennial Man', Zen and ORAC from 'Blakes 7', Twiki and Dr Theopolis from 'Buck Rogers...', Ziggy from 'Quantum Leap', Proteus IV from 'Demon Seed', Max (compliance!) from 'Flight of the Navigator', Huey, Louey and Dewey from 'Silent Running', Johnny-5 from 'Short Circuit', T-800 and T-1000 from 'Terminator' series, Sonny from 'I-Robot',
