The concept behind Dell's luggable XPS M2010 harkens back to the early days of the PC era, when just about anything smaller than a mainframe could be considered a portable computer. The original Compaq Portable, seen here, even matched up to the new Dell in price ($3,590, according to Oldcomputers.net) and weight (OK, at 28 pounds, it was still a little chunkier).
For that price, back in 1983, you got this: a 4.77MHz Intel 8088 processor, 128K of RAM, two floppy drives, a 9-inch monochrome monitor and MS-DOS.
