So what is implied, I think, is that despite earlier reports to the contrary, everything has sucked for Mac users up to this point. And, by extension, everything in the future will always have been sucking. Therefore, everything, including these superfast new Macs, already sucks as it is pretty much a given that new technology will arrive to eclipse the old, revealing the suckiness that, ipso facto, pre-existed the condition that revealed it.
PC users may stop chuckling now, as this cycle of “has sucked-will suck-will have been sucking” affects all tech at all levels. How many times can you slap a paint job on Microsoft Office? How many times can you rerelease iTunes in a three-month period? How many angels can dance on the head of a pin? No, dude, a lot.
