Nancy, who is a professor at State University, does some of her writing and class preparation at home at night. Her department provides faculty members with a $1,500 allowance for a desktop computer for use at school, but does not ordinarily provide computers for use at home. To have a computer for use at school and at home, Nancy has asked the department to provide her with a notebook computer that costs $2,500. The head of her department is willing to provide the standard $1,500 allowance and will permit Nancy to purchase the $2,500 notebook computer if she makes a donation of $1,000 to the department. If she acquires the notebook computer, Nancy's home use of the computer will be approximately 60% for business and 40% for personal use not related to her job. Discuss the tax issues that Nancy should consider in deciding whether to acquire the notebook computer under these conditions.
