I deal with this by saying that this is what you know if you have computer-0. Basic tasks and little more, but could learn with more effort (and likely more effort than most people will put in).
Agreed. The universal rules on skill checks is also something I also modify from player to player; 'look up someone's outlook diary' on a desktop (let's assume you've snuck into someone's office or something) is a task so trivial I wouldn't make you make a check to do it
unless you don't have computer/0 (TL5/6 homeworld or something). At which point it clearly is a significant task and hence success or failure becomes interesting - because, even assuming you understand in principle what a computer is and how to use it, not really knowing what you're doing, you'll take longer and unless you concentrate and think carefully, you'll make errors that result in annoying (and audible) bleeps, leave the windows in such a configuration as to make it obvious what you've done, etc, etc.
The task is still trivial and as such should have a +3 or +4 or more, but once you drop in a -3 for being unskilled and don't allow people to take their time, it can be difficult. It's the same as my view on piloting - pilot checks become interesting (and needed) when the man at the helm
isn't the party's pilot (because he's injured or something).
I agree that anyone from a contemporary western europe/north america equivalent plus will probably have computer/0. But I would say "so take it as part of your education skills, then", in exactly the same way low-tech can (and normally would) take survival/0 - "what do you mean, how do you start a fire?". That said - whilst I agree with F33D (I've used Unix computers, for example, and am devoutly grateful I don't have to on a day-to-day basis) that the skill needed by a computer user has gone down, I never considered Computer/0 to include coding/macro/html type skill anyway - that sort of thing would be more a skill/1 type task, because it implies more than a passing familiarity with computers.
Admin to me strikes me more as the 'dealing with bureacracy/forms/logical organisation of documents' skill rather than 'secretarial skills' of using Microsoft Word Aslan Edition*.
