The point is still valid...it isnt easy for the average person. Plus people who aren't computer savvy are also going to consider Bitcoin as "difficult to use".
Granted, you do have a reasonably valid point. However, a Bitcoin client isn't
that much more difficult to use than a web browser, really. Actually, if the average joe
can drive a car or fill out a tax return (yikes!), they can definitely install and use a Bitcoin client
if they so desire. That latter stipulation may be the tricky part, though.
People will get it perhaps in the next year or two. But to pick up a new concept like bitcoin and put your full faith into it on a whim is stupid.
It took me about 8 weeks to get the concept of bitcoin down so I understood how it all worked and was able to test it out before delving into it as an investment.
The average joe will not wake up as fast to this new system. Most of us were born into the paper/digital money system.
