all i can say is splurge and go wireless: mouse, keyboard, audio, internet, etc..
in america, you can write them off as a business expense, then depreciate their value as further in later years.
not sure how canucks do that.
how many pucks can you write off lost in a spring thaw?
A wireless mouse might be a plan. Hmm, wireless numeric key pad? That might actually work. Here in Canada we depreciate that stuff and call it "capital cost allowance".
