Comparing Electronic Capability Costs: 1991 vs Today

MJ Perry does an excellent job comparing the cost, functionality and power of electronic functions in 1991 vs Today:  1991 Radio Shack ad: 13 electronic products for $5k (and 290 hrs. work) can now be replaced with a $200 iPhone (10 hrs.)    Do see the comments, which correctly make the point that there are hidden costs not included in the iPhone analysis.  Still, very well done and dramatically shown with the Radio Shack ad.
