depends on what you are trying to show for your business. If you are trying to buy a house or anything bigger, and want to show you are making decent money, then more write offs isn't gonna help, because that will show you made less money. If you are truly just trying to get the tax deduction for your business, then go ahead and buy it and write off the whole thing all in one year.
