A crumby old black figure 8 connector doesn't really compare to the wonderfully engineered power supply unit that Apple have provided with their laptops until now.
I honestly think Apple have misjudged this. It's always been the little things, such as the two options for the power brick, which have helped keep them in such high regard with the masses and give the impression of real quality when you purchase an Apple product. Mac Minis are also no longer supplied with display adapters.
Obviously a numbers guy at the company has crunched the numbers and said 'We can save $X-million dollars if we stop supplying the longer cable which only x% of users use'. To me, though, that's really not Apple. Or at least, it shouldn't be.
