No kidding. All my favorite characters had the "Blade" skill.

Hacking in the Traveller universe mostly doesn't exist. Remember, the game was first published in 1977. In those days, hacking was called "phreeking" and it was done on the phone system, not computer networks. Personel computers were a rich nerd's hobby and none of the famous hacker attacks had happened yet.
So, to be true to the genera, we assume that for the most part computer security works AND any really IMPORTANT information is on isolated systems.
On the other hand, IMTU everyone has a Pocket Computer about the size of Palm Pilot with the whole New York Public Library stored on it. The Pocket Computer has a voice interface roughly the same as the bridge computer from the original Star Trek. As GM, I use it as a plot device to pass info on the the party.
It also makes finding good Varger resturants easy, and can display walking directions.
