I'd say it depends on what you want the software to do for you.

I would have liked to see how a plan looked like, especially for cases 
like: 
Activity 1: You have a presentation to do at 2 o'clock for 2 hours.
Activity 2: You want, say, 7 hours to prepare.
How do you schedule these, and how do you show the dependency?

How do you control it 'to the second' if you don't know when it's 
going to be finished? (except sometime during the day)
Hmm, maybe you mean the effort here?

Maybe I'm just slow, but well, as you probably can see, I'm still 
unsure, a bit confused and not quite certain of what benefits and 
restrictions this way of working gives :)
But I'm quite sure it should be possible to incorporate this work 
model also, I think it's more a question of finding a reasonable ui 
that covers it all.
