Thanks johnel for the extra comments.

The black case is a bit garrish hence why I think I may try the clear case, especially for the screen res increase.

Also - I've tried fitting my n900, with the gel case on, in my waterproof housing like this one:

And fits very, very tight but I an actually use the screen controls. Press on.off was touch and go but am now really happy as this waterproof case is the best one I have found so far.
