Microsoft’s approach with Windows, and backward compatibility in general, is commendable. "Users can install new versions of this OS on old machines, sometimes built on a mishmash of components, and still have it work well. This is a remarkable feat of engineering. It also comes with limitations—as it forces Microsoft to operate in the past." Bu Apple doesn't share this focus on interoperability or legacy. "They restrict hardware options, so they can build around a smaller number of specs. Old hardware is often left behind (turn on a first-generation iPad, and witness the sluggishness). Meanwhile, dying conventions are proactively euthanized," says Karjaluoto. "When Macs no longer shipped with floppy drives, many felt baffled. This same experience occurred when a disk (CD/DVD) reader no longer came standard." In spite of the grumblings of many, Karjaluoto doesn't recall many such changes that we didn’t later look upon as the right choice.
What about the change to Helvetica? It ties to the only significant point in yesterday’s iMac announcement: Retina displays. Just take a look at Helvetica on any high-fidelity screen, and you see a crisp, economical, and adaptable type system. "Sure, Helvetica looks crummy on your standard resolution screen," concludes Karjaluoto. "The people at Apple are OK with this temporary trade-off. You’re living in Apple’s past, and, in time, you’ll move forward. When you do, you’ll find a system that works as intended: because Apple skates to where the puck is going to be.""
