First thought: If you have 3 essence left you are not a sammy. You list a lot of high end bio gear not available at character gen. Sure if you have access to all the bio in the book from start you can afford to rely on stats and skills and pat yourself on the back for it.
Second Thought: I for one believe you can have a discussion about agumentation costs without dicussing adepts. Don't get me wrong I believe there has to be either parity or distinction between the roles of sammy's and physical adepts.
I thought a Sammie was defined by his role, not by his gear. Next you're going to tell me he's not a street sam because he doesn't use a Katana? Glad to know you're here to set me straight about character roles. ;-)
You certainly CAN play a sam with 3 Essence. You don't HAVE to max out every stat with ware to be effective. This one is an Orc with a Bod 6(

, Str 5(7), Agl 5(7), and Rea 5(7). No cyberarms with maxed out Str. No Wired Reflexes. He does have couple of really good dice pools, and enough skills to be useful in other areas. He regularly takes out heavily armed and armored Trolls, without relying on too much ware. In our game he works. In yours? Maybe not. But I'm not playing in your game, am I?
Second thought: I only bring up the Adept discussion because it so closely parallels this one. 'Phys Adepts are -because of the high cost of powers, especially when compared to sammies and their cheap ware'. 'Street Sams got hosed because of the high cost of ware'. I brought it up to point out what I see as hypocrisy. This is just my opinion, keep in mind, but it looks to me like a bunch of different groups of people(with a great deal of overlap) are all complaining that their favorite archtype got nerfed and is not as powerful as they'd like it to be. Buncho stat crunching munchkins. The fact that you insist a sammie max out his Essence implies to me you are a munchkin.
Note that I am not putting a value judgement on stat crunching munchkins. If that's the kind of game you enjoy, then good on your for having fun. But don't insist the game be changed for the rest of us. We don't need lowered Phys Ad power cost(though I agree Crit Strike got necessarily nerfed), and Cyberware does not need to be made cheaper or more available, not for every group.
