I have a log on my PC. It's called "Recent Documents". But if my recent 
documents ran to dozens of pages it would be much less useful.

I think you're missing my point though. In usability we can talk about 
"affordances" [1]. Sugar has none. I cannot work out how to use it 
because I cannot by looking tell what any particular part of the user 
interface is supposed to do. Or I guess but I'm frequently wrong. Some 
of the applications are a lot better than the UI as a whole in that regard.

Or another example - 90% of things don't have tooltips. The one or two 
things that do and which take quite a long time to appear just serve to 
frustrate you more in the vast majority of situations when you really 
need them and they aren't there.

I'm quite sure the developers have worked hard on it. But it's being 
used because that's what people are being given. It's being improved 
because there's still money behind it. I don't think that proves 
anything, and even if the developers have worked hard, they've gone off 
on some wild tangent.

It's often said that most programmers suck at HCI, but at least most 
programmers know to copy designs that work. You'd have to be pretty 
arrogant to think that you can design a better GUI than what the entire 
industry has researched and developed over 30 years.

I haven't seen the hardware.
