What I find frustrating about Zinio is their software. They announced their upgrade over a year ago and fixed none of the limitations. There should be an analogue zoom option, not just 1/3 or 1/2 page. Other controls are not user friendly and they have a habit of announcing something and then covering it up as though they never mentioned it. CPanel has fantastic controls yet a corporate entity can't come up with anything better. Their DRM can be a pain also.
That said, I use them.
