About a decade ago I had a conversation with a Comp Sci Professor about this, but in the other direction.
There is basicly nothing you can come up with that can't be improved by slapping a computer and wireless capablity on. From chopstics to mega stadiums, putting a computer on something can ether improve it's function, or give perpheral advantage. That advantage maybe as simple as not letting it get lost, or just adding a "cool" appearence, but it is in engeneering terms a measurable, traceable advantage. With our ability to print transistors only a couple molicules wide what can't we add a computer too?
Armor? Biomonitor built into using a distributed micro sensor net; a great idea. Built in drug dispencer, big improvement. Don't forget a panic switch to doc wagon. Helmets? so much stuff you can do there, communications, sensors suits, entertainment, direction finding, not even starting on skill decks or anything along those lines.
Weapons! Of course your gonna have them active, why? For the wireless bonus of course. Symbolizing the millions of things you can do to improve accuracy with better tech. Smartlink- a range finder, combined with a gun cam, a HUD, and some decent software to put it all together. Puts a target radical where ever your pointing your weapon, and tells you how to adjust for bullet drop, drift and silmiar issues. You know the pentagon has smartbullets already? Bullets that literally change diretion to hit their target, just imagen how much that tech has improved by 2070. Even melee weapons be improved, Mono-whips? Auto-retract on a miss instead of taking of a limb? Amazing! They never found a good wireless bonus to put on a sword, but there are other games that have done so. Core Command which is a great scifi game, had a sword that rebuilt it's blade every time you swung, adding properties to the weapon each time you hit the opponent. Admittedly that tech is to far out there for SR. But having your sword make lightsaber noises and glow could be a "Cool" feature many folks would eat up. Or competition fencing using sensors to determin who actually hit first, or golf clubs that tell you what was wrong with your stroke etc, etc.
Vehicals- You know cars really drive themselves at this point in SR? Not having your car connect to the grid is in many cities can be cause to get you pulled over. Sure this dosen't hold true in the really, really bad parts of town, but never fear the cities grid will advice you strongly not to go there.
Cyberware- Over the last decade we have made huge leaps forward in prosthetics tech, but we are just beginning to reach the cave painting stage compared to SR cyberlimb capablity, not only does SR cyberware restore full capacity, it improves it. That is to say the new limb offers better dexterity, greater strength, greater endurance (Including super human levels of all three of these), but it also includes a high level virtual feedback, without that sensory feedback it couldn't do what is dicussed. Adding many other capabilities to cyberware simply means even greater improved capacity, Guns, Blades, Commlinks, smuggling compartments, all things it's easy to understand adding to such tech marvels.
Finally mages and adepts are still people, meaning that they would enjoy using all the modern convences of the time. Being a mage or an adept doesn't mean your anymore likely to declare yourself a hermit and try and live alone in the hills. Modern tech is wirelessly connective for all the reasons discussed above, and it works better for it. Sure there's the SR equivalent of Jack Reacher out there somewhere, but he is the exception that proves the rule.
