Everyone wants new gear, but how much is too much to spend? Gizmodo’s “15 Most Overpriced Gadgets of All Time” features appearances from some recent offenders, almost all of them tablets, including the Motorola Xoom ($1,079 with two year contract), and the BlackBerry Playbook ($499). It also takes a look at some products of yesteryear with Apple’s Lisa, launched in 1983 for $10,000 (that’s $22,000 in 2011 dollars), and AT&T’s VideoPhone 2500 from 1992, which cost a whopping $1600.
