i think it's time for a new keyboard

i've worn off a lot of the letters on my keyboard. it doesn't bother me, since i don't look at the letters when i type. but it really freaks other people out when they see my keyboard or have to use my computer. tech support hates me. the letters that are worn off are: e; r; t (mostly gone); u (mostly gone); s; d; f; h (mostly gone); c; v; and m (mostly gone). here's the weird thing, though, the letters aren't worn off evenly or even in a pattern that suggests use of more letters than others. more letters on the left side are worn off that the right. and yes, i am procrastinating, why do you ask?
