On Vista1.html, I'm nclear what is meant by "wordless bead", and the accomanying graphic doesn't seem to answer that.
The graphics seem too compressed to be fully readable, at least on my laptop (1280x800). Perhaps you could make them clickable to a larger image?
When you're fixing Joe's Breadcrimbs, you might want to change "systen" to "system".
On Vista3.html talking about RSS feeds, you say "nust in case"
Not a comment about your slides, but about the OS:
Putting Logoff next to Shutdown and not requiring a confirmation prior to shutdown seems to be a poor choice, IMHO. Perhaps it's not a simple matter of a slip of the mouse to select one as oposed to the other; its hard to tell without trying it.
On "Mixed Content" (Vista3.html), you don't indicate whether they've added the ability for the user to "opt out" of the warning message, as they can so many others. From a system administration standpoint, it makes no sense to encrypt non-sensitive graphics, given the high CPU costs of doing so. Yeah, it's not particularly germaine to your slides; I'm just interested.
"Help is hiding at the right edge of the ribbon under a chevron symbol." Ugh! That's exactly where a neophyte user who needs assistance is going to look for it. NOT!
The only overall comment I have is that it is more geared to something that people will look through themselves than to a presentation, where you would probably only want to include bullet points you can talk to.I generally find that management, especially higher up, wants fewer details and more bottom line. But you have to be ready with the details in case they hear something they want to delve into! But you obviously know your management much better than I do, so act accordingly.
All nitpicking aside, it's a great article! Good job!
BTW, I had no problems with Firefox 1.5.0.7.
