That is a beautiful stand, by the way. I covet things like that, I just wish they worked for me.
It is super-difficult to be ergonomic with a laptop. Your neck may feel better, but you may still be rocking a head-forward posture that will hurt you down the road and your shoulders may be still curving more inward than they should. For me, having the laptop screen and keyboard so close to one another doesn't work: either my neck has to bend forward, or my arms are too high. To get that ooh-aah ergo feeling, I have my laptop boosted to a height that works for me, which is higher than keyboard level.
To combat the forward shoulder thing, I've got two keyboards and I can move them around for variety as long as I follow alignment rules. And despite what someone said about not being able to type with two keyboards, these are playing together very nicely: an old Dell standard keyboard and a newer E-Element Z-77 mechanical are attached and typing together without any issues on an older Dell Latitude. The keypad on the actual laptop was having some delays, but that was ergonomically sucky using one keyboard plus the laptop, so it doesn't really matter. I'm sitting right now, but I'm going to try the double keyboard thing later when I move this experiment to my adjustable height table.
