Actually. I really like the idea of Online designer for web design. I have done some wordpress sites for clients and it is too complex for some of them. A xara solution where I can design without limits and allow them access to certain areas to update text or galleries is a good thing.
XDP is my swiss army vector tool but without proper cmyk handling it is rubbish for anything to do with print. Web or ebooks would be another matter entirely. With that in mind I personally think that using Online Designer for print work would be pretty limited.
So. Yes. I want to use Online Designer for web work :-)
