Set the clock forward a bit - Same city - same show.. several years and a stint of military service later. I see a demonstration of Windows (3.1?) going on. Amoungst the 'oohs' and 'ahhhhs' of the crowd there is a single unimpressed ex-soldier sitting there... 'That ain't no big deal' He says.
'What?'
'That ain't no big deal - Does it multi task?'
Man clicks open Word and a clock - 'There, need any more proof?' (crowd nods it's approval)
'Did the clock stop when you clicked in word?'
'Ahm ahhh'
'Can you run word, unpack a disk, connect to a bbs, run a paint program, and assemble 300k of assem code at the same time?'
In a flurry of mouse clicks the demonstrator tries to open everything he possibly can, before being met with a 'general protection fault'
He then waves over to a few security guys who kindly ask the ex-soldier to leave.
The one I used to like was starting a floppy formatting, then drop a few files onto it while amusing myself with other parts of Workbench. The PC (l)users would stand agape!
What's more, formatting a floppy under Win2kPro these days still kills everything else.
