Dell Inspiron 9100: $4,800 Pentium 4 Laptop from 2004

Among mid-2000s Windows XP notebook computers, the Inspiron 9100 was thoroughly into desktop replacement territory. Dell gave it a full desktop Pentium 4 CPU, a 16:10 HD display, and even a built-in subwoofer! What a hot and heavy beast of a gaming laptop, portable workstation, and media center all in one.
