I don't see where overly-complicated apps with poorly designed user interfaces promote productivity, but I guess that's just me. Or maybe I've just had to suffer through one too many lousy PowerPoint presentation and had to read one too many disheveled Word document to agree that features and productivity are the same thing.
And I have, over the year, had to deal with so many Word documents that self destructed after a certain point. It has gotten better, but the 'good old days' were filled with 'blown' Word documents that you either couldn't open anymore, or they just freaked out during editing or saving them.
I LOVED telling people that it 'just happens' from time to time, and for 'complex' documents. The next question was 'what does complex mean? What did I do to make this happen?' And I couldn't tell them... I loved the crap out of that part...
