What keyboard is everyone using with their MacBook when connected to a monitor. I bought the new small Mac keyboard and really like it except for the white keys. I used it for a week with no problems, then over the weekend when reading the newspaper and surfing the net the black from the newsprint rubs off on the white keys ... looks like 'pigpens' keyboard now. Can anyone suggest any other good (small) external keyboards? What keyboard are you using? Thanks.
