Smartlinks are generally better than they were in SR4, since a +2 dice bonus is harder to come by. Of course it's still no SR3 Smartlink, which for a TN 6 (modified to TN 4 by the smartlink) shot had the roughly equivalent outcome of tripling your dice pool.
smartlinks in SR5 are only better (comparatively) if you actually have them wireless, which has a bunch of potential drawbacks. including losing the full use of your smartlink. and, depending on what else is attached to the device that your smartlink is on, your ability to see.
and no, it's pretty obvious that skillwires have indeed been retconned. the 4th edition version needed no skilljack. all you needed to run a knowsoft was a DNI from any source. not so in 5th. we can safely say that the devs looked at 4th edition skillwires and decided that no, they don't work like that anymore.
furthermore, it is *extremely* obvious that skillwires got retconned, because we know *exactly* what old skillwires are like; exactly like the current ones, only not wireless-enabled. not sort of like the current ones, but needing different pieces of equipment to function, and an order of magnitude cheaper. SR4 has pretty clearly had it's augmentation costs errated out of existence.
edit: oh, and by definition, if someone is willing to do business with you, well... here's the description of a loyalty 1 contact:
"Just Biz. The relationship is purely mercenary, based solely on economics. The
people involved may not even like each other, and they won’t offer any sort of
preferential treatment."
so as a matter of fact, yes, if the guy who installed your cyberware is willing to install more cyberware into you in exchange for money, then that guy is a contact.
