[BNM] Question for laptop users

[Jonathan Hirsch]

Hi all,

Just out of interest, what do you use, if anything, to prevent your  
screen getting covered in keyboard-shaped muck?

The foam keyboard cover thingy that came with my MacBook is getting a  
bit knackered (probably not helped by me regularly rolling my chair  
over it - by accident, obviously). Apple sells something for £15,  
which I don't mind paying if there's actually any advantage to it  
over, say, a cut-to-size piece of greaseproof paper from the  
kitchen... ;-) Just wondering whether there's any particular product  
or type of material that's best to use. Any thoughts?

Cheers,

Jon
