You have too many big bubbly shapes in your spec. It's too visually noisy overall. Clean this up, take only the normals that show form and a flat color diffuse and work up carefully on diffuse and specular. Less is more in the case of materials like this.
This is looking really cool man, but a lot of the details are being lost with the diffuse and spec as others have mentioned. I'm interested to see how you fix it. BTW, did you bake AO?
The high res could do with alot more details and the low res with some more geometry, for instance some of the side details aren't coming through very well at all and overall a similar effect is seen which is affecting the whole shader. Losing that keyboard at the top would be beneficial to design as suggested, instead add…
