Does anyone care to comment on a "rubberized hard plastic case"? I've been thinking about going this route, as much for shock protection as much as for textured grip and scratch/cleanliness issues.

Something like this

I know the PDair gets mentioned in the wiki

but it seems to be the exact same thing, at four times the price, plus shipping.

Mostly I'm interested in hearing any comments from users of this type of case - keyboard/outlet access, ease of sliding, etc.

Thanks you all
