You still have to choose what language to install prior to purchasing Windows. It comes in one language and only one. OSX is
distributed in all major languages.

If you launch the installer from the DVD from within Windows, it won't give you the option of erasing the startup disk. You have to boot from the installation CD. OSX only installs this way, if you run the installer from the DVD it gives you only one button; restart. Why can't Windows do this? Why, because the bot order is set in the bios, and can't be changed by the installer software.

The installer asks to fetch updates before installing. That's a good idea, then I don't have to run the update cycle after the installation. This only works if you upgrade and run the installer from Windows. If you boot from the DVD, you're out of luck since it doesn't ask you about your network prior to this step. Intelligent isn't quite the right word to use here. OSX asks you for network
information before letting you set up .Mac and such (albeit doesn't download updates).

After two reboots (not counting the first), Windows Vista checks my computer performance... What's with all the reboots? OSX handles the install with no reboots. It's just annoying. During the check, which takes several minutes, about five or six advertises loop on the screen.

After login, three gadgets launch and the "Welcome center". I tried out Flip 3D which shows the desktop as a window, and the welcome center, all floating above.. uh, the desktop. So, to Windows Vista, the desktop is a window? I suppose it makes sense in the "everything is maximized" world of Vista, but it's just badly implemented. If you have several windows maximized, which most people do, and select the desktop, *every* window is minimized to the task bar. To get back, you have to go and un-minimize them all, one by one. Exposé really really rocks.

The task bar, without any third party utilities, has really really ugly and cluttered small "taskbar icons" for battery, network and
such. It really looks like WIndows 3.11 still.

Window redraw is slow. The entire interface is very sluggish. And this is on a Dell XPS laptop that manages 192 fps in DOD:S. Windows skip around like crazy when moved and more sluggishness feeling is added because of the fade in/out effect of windows. This is worse than OSX 10.1, but maybe not worse than 10.0

In the welcome center, there is a button for "Windows Ultimate Extras", which when clicked changes the head and reveals a button,
"Visit Windows Ultimate Extras". Apart from the fact that this is horrible UI (i.e. click a button that reveals something above it that
has yet another button) this second buttons takes me to Windows Update that checks for new downloads, which doesn't contain anything related to any "Ultimate Extras". Wo whatever these "extras" are, they don't seem to actually exist yet, unless the language packs count as extras

When I select to install an update, the screen dims and it asks for my permission to download and install the updates I just selected and
wanted to download and install. One extra click, and not even an authentication, because my password wasn't needed. Just a click.
Heh. This step repeats once. During the install, there is a "progress" bar that has a fading color looping across it. It's the usual
"something is happening, we just don't know how much we've got left", which is ironic, since the progress is also reported in percentage in text right beneath it. Haha.

Finally Windows can playback DVDs! Welcome to 1996 Windows, you're just over ten years late!

And, one of the gadgets in the sidebar is "Feeds", which only shows feeds you've subscribed to in IE, which has no subscriptions out of
the box, so it's just an empty box. Hehe.
