Release 5.0 Information (Help!)

Greetings netters, Are there any Informix 5.0 users out there who are willing to share their experiences about the product? Informix rep told us that there are not a whole lot of their current customers jump on the 5.0 release yet and recommended us to use 4.1 for our software. What's holding up the conversion process? Are there unusual things to watch out for? I am mostly interested in the UNIX workstations and servers area, but any information about the 5.0 release would be helpful. Thanks in advance!
