You guys are thinking of this all wrong. The reason the processors don't do things like they used to is because the corps have purposefully downgraded their processing power in exchange for the ability to control the flow of data and power via their Matrix. Remember that GOD is separated from the corps only by the thin red line of bureaucracy. The corps still own the Matrix, we just borrow it from time to time.
Also, you have to accept that what wireless is used for now might not be the same as it will be a hundred years from now. I get that the medkit is the prime example of why wireless bonuses make sense, but that's only because it makes sense to us now. Most of the wireless bonuses are there for two reasons: to encourage players to use wireless at the risk of being hacked; and to provide a skill point bonus that isn't otherwise there. The limit is increased regardless, but we're talking about 1 or 2 dice, which isn't even a success (statistically speaking).
It's not game-breaking, it's a mechanic with a purpose, and even if it's not 100% logical it still has that purpose. And also, it's possible that Data Trails might utilize this mechanic even more. So let's not argue about whether or not the wireless bonuses belong in the game because we don't know the whole story. Let's instead argue about whether or not the bonuses are game-breaking, unbalanced, etc. Since this topic is never brought up, I can only surmise that no one thinks the bonuses are really all that bad. We're all just looking for something to disagree about.
