I worked with a company that used Lotus Notes and I must say that it is the worst designed, most cumbersome and simply dire package I have ever used. It was unspeakably, laughably, mindlessly badly-designed. It was so bad I cannot understand why it is still in use. If good design has its reward in devoted fan-boys and girls, satisfied and loyal costumers, and basking in the warm glow of memory, bad and poor design should be consigned to history's dustbin and assigned to oblivion. As others who have posted on this thread have remarked, it makes all of the MS software look effortless and flawlessly designed by contrast. I cannot believe that anyone in their right mind - with function, ease of use, basic competence as criteria (rather than profit) - would ever seriously installing and using it in anything, be it a company/institution/or a revolutionary piece of design.
Another thread discusses whether, which and why people have or do not have iPhones. I'm a long time iPod fan and recent MBP switcher, and am very happy with these parts of the Apple world. Currently, for a variety of reasons, - restrictive contracts, limited functions, high pricing, - I don't have an iPhone, but am open to conversion. If, however, Lotus Notes becomes the standard, then, that is one Apple product I will never contemplate switching to. Words fail me.
Cheers.
