Yes - this is what we are doing. With this 4x cost differential however, we calculated that it takes only 6-8 months to have the hardware pay for itself, so if you plan to be in business in that time frame you are better of buying.
I guess that the best would be to use EC2 in the beginning, when you don't really know how much hardware you need, and later on use EC2 only for demand spikes.
