Apple planning to take on Exchange?

I just got spammed by Apple to take part in a Web Survey which although ironically amusing:
Our records indicate that you have purchased a PowerMac in 2001 . Do you still use this computer?
Which of the following best describes your current employment status? (Please select all that apply)

went on to ask lots of detailed questions about the Calendar software I use both at home and work.

It didn't give an opportunity to say what I did like about iCal (open file format, easy calendar publishing, easy to incorporate conference schedules) or what I dislike (UI is still really clunky and frequently messes up on my intentions), but asked lots of 'competitive analysis type questions.
