Keep in mind it isn't always metagaming or "unrealistic" to not have points in certain skills; Computer, for instance, isn't needed for a character to do basically anything a common user would do on a commlink, save for maybe a Matrix Search or Matrix Perception test. Not having points in Computer doesn't mean your character doesn't know how to use a commlink very well; it just means they don't know the technical side of things like editing, advanced options, and so forth.
Another common thing is that some people think it would be weird for a character to not have any points in Pilot Groundcraft. However, day-to-day activities do not normally require rolls. A person manually driving from their garage to a restaurant won't require a roll; very little outside of deliberate stunts, extreme driving conditions, and chase combat require a roll. On top of that, in 2076, every car comes equipped with an autopilot. Licenses aren't required for a car's autopilot (assuming it is up to date and functioning properly) to drive you somewhere, so many people don't need to know how to drive.
Those are just two examples, but the point is that spreading out a bunch of skill points into very minor "civilian" skills isn't necessary for your character to still appropriately reflect the world they're in.
While you may get more karma from the massive number of potential skills at high ratings you can get from Skills A, keep in mind the relation of attributes to skill dice pools. A skill point is only ever a +1 to a dice pool (if it isn't a +2 from a specialization). But attributes can vary; +1 to AGI is +1 to over 15 different skills, while +1 to BOD is only a bonus to two skills (but several other vital statistics).
