Polished? You're kidding right? This is a genuine question on my part, open to all. In Win7, if you have a VPN connection live, you could see it in the notification area when you clicked on the network notification icon. You could choose to connect to the VPN, or, indeed, disconnect. This is no longer the case with Win8. You have to "hangup" the adapter manually. How is this polished?
Windows 7 was polished
What's the definition of polished.
I think the desktop is pretty good.
I think WWM (What Was Metro) is still a bit raw. Customisation options are pretty basic, tile layout etc.
The universal Search is a great concept, but needs a bit more work on it, particularly about what you choose to search (i.e. all apps/files/settings v. selected app/file/settings).
Microsoft Account profile sync kinda works, but it's fairly confusing what does/doesn't sync and whether this works reliably. I.e. some web logins do sync across machines, others do not. IMO for this to be polished there'd be options to sync everything...
Store. If you look at "Your apps" there's no way to remove items you've previously installed. This is going to be a mess sooner rather than later. No simple way to move the App installation directory, which will become relevant over time, particularly for those using small SSD boot drives.
Multi monitor support. Some great improvements, but the corner detection points are not particularly intuitive. Nor when you drag an app down to close it and it moves it to another monitor (I'm running 1 above 3 monitors), then moves your start screen.
Drivers. MS have not been as pro-active with partners as in Windows 7. I've previously mentioned the state of the NVidia Surround drivers, but am also aware that Asus Xonar drivers are not available. Probably many others.
These are all relatively minor points. I like Windows 8 and I can see it's potential, but I think there's still a lot of polish required. I'm guessing we'll see that with Codename Blue.
