I have been running Zimbra for several months now having migrated over from Scalix.
One of the main reasons for the migration from Scalix was the web interface. The great looks and performance finaly won me over despite loosing the ability to use Outlook. When I am away from home I enjoy using the Web interface but whilst at home I have to confess that I find a desktop client preferable. Now I think Thunderbird is great and is probably my client of choice however it doesn't support contacts. Evolution is ok but I'm not over enamoured with it so this leaves Outlook. Now I know that the Zimbra policy is different to Scalix in that they don't give the ability to use Outlook with the community version. I fully respect this and am thnkful for what I do get to use for free!
Having read the specification for the Network version I would be more than prepared to pay for it as a private user if there was a personal edition available. This personal edition would contain all the features of the Network version but be limited to say 5 Outlook connectors. I have considered purchasing the 25 user version but really can't justify the cost over the benefits given that I only have 4 users.
A search through the forum did throw up a similar request a couple of years ago however I think the question then was more if a free personal edition was viable. I am happy to pay for a reasonably priced personal edition and was wondering how many others would be willing to do the same?
