I completely agree -it's not and that's what makes it magic.
However it's only not "simply backup" for about 10Gb of your files. For files you don't sync onto other machines it is by definition simply backup. Moreover it's the backup service that you're considering in your mind when weighing the buying decision of whether to spend an extra $100/year on it. It's not $100/year more of seamless multi-machine syncing.
I can only speak from my own experience but while, as a consumer it was the usability of the software that hooked me, it's the backup I pay for. That may not be the case for a business but it is for me.
