Don't just take our word on it. Consider what MicroFocus recommended when they still owned the Reflection product line.

When evaluating terminal emulation solutions, MicroFocus® suggested that customers ask themselves five questions:

1. Is the vendor committed to terminal emulation?
   We sure are. While we offer a few other products, ZOC Terminal is our main product, bringing over 90% of our sales. So yes, we are committed to bringing you the best terminal emulation product we can, because this is the essence of what we do.
2. Does the vendor have a history of technological innovation?
   We sure have. ZOC dates back in the 90's when a terminal emulator was a window and not much else, we introduced a few features to the market that were quickly adopted by our competitors. Even today ZOC offers some unique features that few other terminals can offer.
3. Does the vendor have experience and staying power?
   We have been in the terminal emulation business since 1987. Is that long enough?
4. Can the vendor meet your technical support needs?
   Every support question you have will be answered by a programmer that has access to the source code and the authority to make a new build available (e.g. a version with a bug fix) or to introduce a new feature.
5. Will the vendor help you navigate the standardization process?
   Okay, we admit it. We fail here. We don't have a four-phase migration guide and checklist. But you get the same support pre-sales that any licensed user will get. By a skilled programmer (see 4.).

Now, after answering all of MicroFocus' original questions, we have one of our own:

If we are a competent and trustworthy vendor of terminal emulation, even by our competitor's standards, why would you pay more each year in maintenance fees for their product than what you pay for a full and ongoing perpetual license of ours?
