The iPad and other devices are not here to displace the PC (by
which I mean all personal computers, whether they’re Macs or PCs
running Windows). In fact, post PC means after PC, a new
generation of products that build on the PC. What it doesn’t
mean is sans PC, that is, without PC. The personal computer will
no doubt be with us for a very long time… but that doesn’t
mean we’re not in the post-PC world.
