Old blades are easy to setup. I can have one setup and running in under 5 minutes and then you don't ever have to touch it again :p
i would say that for a technical capable user they are easy. but if you are a complete novice stick with the usbs. i have had people who did not know how to change their local ip to match 192.168.1.x ... hurray for teamviewer!
if you can set up a home cable/dsl router without using the 'easy button' then yes old blades are easy to set up.
