Two things:
1. It is so uncool to make the effort to complain about typo's - especially of the intention is obvious.
2. This business about finger prints... Laptops and Monitors are "Utility" devices, they are supposed to be used ! My laptop has fingerprints all over it, who cares really. It is not a fashion statement. If getting finger prints on my screen means enabling greater ease of use, then so be it.
Stop complaining, fix the rips in shoes jeans and do up your shoe laces first, pull up your pants, wear your cap front forwards, stop spitting on the football field, clean the inside of your car windshield, then your Mum's coffee table top (with wax polish), clean up any pee drips around the toilet after yourself, (and the wash basin), then start complaining about finger prints on your monitor.
Please excuse, the slight rant, but common on !!
