aaaaaaaaaxxxxxxxxaaaaaaaa, where the hell did you find that pic erich
Google knows all.
"broken pinky xray"I like the "thumb button" quite a lot too, but IMO it needs to be a slimmer button. The GGTS would look imbalanced with it sticking out of the middle. Atmizoo did a good job with one (at least aestheically). The button is really narrow, but sticks out just enough that you can find it without looking (i.e. nice in the car). It does have a design flaw, though, in that if you screw in an atomizer with the tube out, the whole button has a chance to shift out of place, and you have to fiddle a bit to get it working again (especially Ithaka, because the center pin is adjustable).
There is also the Poldiac, which has the button configurable on top or bottom of the battery. However, the button is completely flush with the device which, while it's nice looking, pretty much forces you to look at the device to see on which side it currently resides. If I'd known that you were planning a new device, I might have tried to get your wheels turning on doing so with the new GG, but there's not really a way to do that without sacrificing the fact that the battery tube is not grounded without the button depressed, which I think is nice. Every now and then, I get a pretty good arc on other devices when I accidentally touch the top tube across the battery and frame.
Overall, the GG button is fantastic and is a workhorse. However, if you could come up with some button design that functioned similarly but extruded from the body about half as much, I'd buy a bag full. It's the only thing about any of my GGs that diminishes its "pocket friendliness".
