"Lighter and faster... for its time."
The successor of the Portable 3, a very expensive piece of hardware for its time. Same body but a big step forward comparing the internal components.
PC Magazine said "Its the hottest thing you can pick up with a handle. At 20 MHz, it outperforms everything else on the market but its deskbound sibling.
