What Act! features are not available in Act! for Web?

This article highlights the differences in the Act! Premium v17 and Act! Premium for Web v17 features. With all the improvements made to the Web products capabilities in v16 and v17, many ACT administrators wonder what they’re actually giving up by not having the Windows client installed on their user’s computers.
