When I began programming in the late 1980s, we learned Turbo Pascal running on 80286s that cost around $2000. I'd call $2,000 worth of hardware in 1980s dollars a pretty high barrier to entry, wouldn't you?
Now your only barrier to entry is a Mac mini and an iPod touch. Both of which can be had for less than $1,000 in 2010 dollars. The real barrier of entry is about 25% of the price we paid in the 1980s.
