It depends on your definition of better. I can't comment on Apple's offering but I suspect your definition of better is feature based. Exchange has a lot of promise (easy server and user integration, if you use small business server it's an easy setup, if you use a standard win server god help you) but it's features are incredibly poorly limited, the performance is horrendous and it's missing lots of basics. I truly have no idea how the money and brains that must be behing Exchange could have so poorly tested the system for usability and real-world use. Outlook again is better than any other email interface I've used. Customisation and filtering and stuff can be a pain and have their limits, and there are some general problem but overall it's not that bad. But one thing that is bad again is its performance - it's terrible! With Xobni, search isn't such a problem (even instant outlook search can be slow) but just opening an email, and eventually the interface is an experience in frustration unparalled for the average user.
