I discovered this article when I was blog surfing: An epic Bill Gates e-mail rant. You can read a email Bill Gates wrote to his employees to complain about usability issues. The email is pretty old now (in computer time), but I'm not sure things improved that much since then...

Best bits:

So they told me that using the download page to download something was not something they anticipated.
Then it told me to reboot my machine. Why should I do that? I reboot every night -- why should I reboot at that time? So I did the reboot because it INSISTED on it. Of course that meant completely getting rid of all my Outlook state.
So after more than an hour of craziness and making my programs list garbage and being scared and seeing that Microsoft.com is a terrible website I haven't run Moviemaker and I haven't got the plus package.

It 's kind of a relief to see that even internally, people know that Microsoft does some things terribly wrong. But it's kind of scary and sad to see that many things haven't changed and won't improve, probably because they're don't care and don't feel threatened by any competitor.

At last, I'd like to react to what the author called "frustrations of everyday computer users". I would have said "frustrations of everyday Windows users". There are other systems out there that simply make updating and installing software a breeze. I will have other opportunities to talk about that.
