Is there any real danger to Outlook and MS Word?

Is there any real danger to MS applications like Outlook, MS word, of being faded out from the way we use it in our office day to day life in office and home becuase of new collaboration tools coming out everyday.

One of these tools Zimbra. even Yahoo acquired it. It completely integrates your mails, meetings, Internet calls, calender, etc. Some of its boosted features other than email include.

• Date hover: Where it can detect words like tomorrow and pop out the date automatically or words like next Tuesday and calculates the day to add appointment for you.
• Contact hover:
• RSS in folders: You can create a folder and set a URL for RSS feed, it shows new topics as new mails.
• View Maps Pop directly in your message windows for directions.
• Approve Reject purchase orders in emails by just right clicking.
• and many more you can check out www.zimbra.com

It boosts having 9 million paid mailboxes and 10 of thousands of customers. They have got an open source version and a paid one also.

It was previously a freshmeat project, and its popularity there is not much only 7-9%.

Although most of the stuff it does is also done by Outlook except RSS folder things. I think, home user wouldn't need it. I tried it, it looks bloated too, to many things at one place, I think we have come to expect simple interfaces thanks to google in earlier days which also now has grown so many legs and arms which we just try to manage [ :-) ].

One going with that, I would like to say that sometimes we worry too much about securing a suitable username in the blog or email address than other real life problems. Few days back, I created a google a/c for my 5-months old daughter to secure her meanigful username. Also, there was a news in the paper about parents securing domain names for their children for the fear of it not being available to them when they are young.

I believe outlook or MS word are embed so much deep in office culture, that it would be very hard to replace it with some thing else. A lot of fellow colleges stare away from even hearing the Open Source word, no matter how simple the software itself would be.

I personally like the software or sites which make life a little easier, and not take up some MB of memory space in my mind for remembering its URL, user name, and an another entry in the things to check on the internet everyday. :D.

Any comments are more than welcome?
