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.
