Your opinion about Onshape

Has anyone of you tried to use Onshape (Full-Cloud CAD | Onshape) ?

If yes, what is your opinion about it ?

Even if it is not as capable as Creo yet, the team is coming with improvements at an impressive pace (releases every months).

Do you know / think that PTC has any plans to come up with a cloud based CAD software ?

Having a cloud based software sounds like it would be a good way for PTC to get rid of people using cracked versions, especially in countries with very "lax" copyright laws...
