I resist change... . Much like my old faithful 96 If it does what you need why change? The only reason I am even upgrading now is that my last xp box crashed and outlook 2k will not work on vista and I need it to keep my phone in sync. So far I am happy with it and when I get a chance will figure out the calendar sharing feature so I can keep track of the whole family and not just myself. Stability wise I have had no problems with outlook or word. Mcafee appears to not have a compatible interface yet, It still scans incoming / outgoing emails it just can not set up its own junk mail box in outlook. The color coded categories I don't like but are easy enough to change back to the categories I currently have
