I have a part-time job doing paper work.Would a laptop be deductible?

I have a full time job and a part time one.The part time one involves nursing home documentation, I don't need it for that- but I do need to track the residents via computer,email and prepare invoices on line and track all of this. in a professional manner. I do have a desk top computer,but its for the whole family and sometimes less convenient.Plus,I could take the laptop to the nsg homes with me. Thanks !!!!!!
