Well, melee operatives can range from "I'm totally DEX based an rely on trick attack, so I don't know why I'm not just using a pistol"
With a Snowgarden melee weapon (Armory), an operative can freely deal lethal or non-lethal damage with no penalty and without having to spend a trick-attack-preventing action to switch modes. Dance-Fu!
It gives the GM an excuse to not have all of the bad guys gang up on the technomancer.
If they miss with their trick attack, they still can provide a flanking bonus. At levels 1-6, they can sometimes benefit from flanking.
With quick movement and uncanny agility, the operative can easily leave melee if it's starting to get scary.
Dragon glands are awesome. They're even more awesome for characters who aren't melee-phobic.
It's trivially easy for an operative to simultaneously wield both a melee weapon and a ranged weapon. Seriously, a competent operative should be able and ready to switch between melee and ranged as fits the moment.
