yup, and they dont last too long, books are still there, yet more rare.
I'm guessing most of the posters here didn't realize that books are still in game, were made much, much more rare so that they're actually exciting to find (as opposed to Fallout 3, where you just knew that any location of sufficient size had to have at least one book an you just had to keep looking until you found it), and now permanently increase skill by 3. I believe the comprehension perk is still in the game as well; it's now just much less obligatory to take now that it gives a 33% bonus to skills learned from books instead of a 100% bonus.
I think the magazine buff idea is great and should provide some much needed flexibility and interest in terms of when to use them. It was always annoying in FO3 to find situations (explosives, terminals, locks, speech checks) where you felt excessively obliged to game the skill system, leave an area, level up, skill up, and come back just because you wanted to get that trap, terminal, door, safe, or speech check completed.
Mini quests like the bomb disarming or the water system repair in Megaton would have been able to be completed using magazines instead of feeling incentivized to modify your character concept and put points somewhere you weren't planning just to move a subplot along.
