Now the PowerBooks are back with the 5300, which offers workstation performance. There are several enhancements, such as infra-red networking, a removable hard disk, a neat, charcoal-grey case and a battery life of three to five hours. But it is the raw speed that impresses most. The basic PowerPC 603e chip runs at 100 MHz, faster than many Apple desktop machines. This power means that for the first time, it is realistic to buy an Apple laptop - and possibly any laptop - that can carry out power-hungry tasks such as desk-top publishing and photograph manipulation. Power Mac optimised software, including Adobe's Photoshop and Pagemaker, runs exceptionally smoothly.
Apple's big problem is of course that its operating system is not the same as that of the far more common PC. It is tackling this by making its machines as PC-compatible as possible. For example the 5300 has PCMCIA card slots rather than the Mac-specific ports of its predecessors; these are used for add-ons such as modems.
More important, the extra power of the PowerBook means it is possible to run a software emulator such as SoftWindows, which in effect turns the machine into a PC. This should prove useful for anyone who has to work with different clients, some running Windows applications and some working on Macs. An Apple weakness can thus be turned into a strength - no PC laptop can run Mac software. It may mean that Macs are not as individual as they used to be, but they are more useful.
