This. This drives me insane. Unless all your peripherals use those skinny apple USB ports, you might as well have only one USB port. And I strongly prefer to select my electronics purchases based on factors other than the svelte ness of their connectors, FFS.I can get by with 2, however on my MBP the most annoying thing is they are side by side, and USB sticks don't fit properly.
Mouse/keyboard can either be bluetooth or use a single port (i.e. mouse hangs of keyboard), but the fact that the USB stick won't fit in the remaining port is annoying.
