There are three things you should immediately know about Acer's Predator 21 X laptop. First, it's hands-down the fastest laptop we've ever seen. Period.
Second, it's the widest laptop we've ever seen: 22.4 inches wide, 12.4 inches deep, and 2.71 inches to 3.28 inches high, front to back.
And third: It's the most expensive laptop we've seen in a long time. Sure, at $9,000, you'd think it would be the priciest ever in PCWorld history, but a 1990-era 286 laptop that cost $6,000 adjusted for inflation would be $11,367 today.
