Check out the Technology Report by Radicati.
The Radicati Group provides research on messaging and collaboration, and more.
"We believe that with the Bonsai release, Novell will again position itself as an innovation leader in the messaging and collaboration market and will offer the true level of collaboration functionality that Microsoft and IBM Lotus are also promoting but which so far has alluded them due to conflicting requirements when it comes to bundling and pricing.
We expect that GroupWise 8 and Bonsai will be well received by Novell’s loyal customer and developer community, but we think its highly integrated functionality will also draw interest from new customers, particularly in the SMB space, which are looking for more affordable and easy to implement collaboration solutions."
Disclaimer: As with everything else at Cool Solutions, this content is definitely not supported by Novell (so don't even think of calling Support if you try something and it blows up).
