E-on is a joke compared to Adobe and Autodesk. 

There is no reason to upgrade every version of any software. There is especially no reason to rush in when upgrading.  There will always be deals later on anyhow.

E-on's long history of BUGS is legendary and world renown.  Just search the internet and see how much negative experience has been reported.  Tons of it has been deleted.

I'M staying with version 6 and thank my lucky stars I never bought xstream.  Xstream is a train wreck no matter what version.

Consumers aren't powerless to upgrade scams.  Just don't buy and we'll see how fast they change policy or extend deals.
