We've leased quite a bit of Apple kit over the years, and it works really well. Not sure what country you're in, but in the UK we've had a few machines on a 2 year interest free lease (effectively, you pay the cost of the machine over 2 years with no interest. At the end of the lease you can hand the kit back, swap it for new kit on another lease or buy it outright for a small payment (typically less than £200 for £2000 of equipment). The advantages of leasing for a business are that you don't have to write the kit off over 3 - 4 years for tax purposes: the lease payments are fully tax deductable each month or quarter. There are also other tax benefits that I don't fully understand (I leave that to the accountants!) but it does seem to work well for us at least.
