Are there any tips not relating to Metro?
Not that haven't already been covered by the vids listed I'm afraid.
The only other 'tips' I have are to do almost exlusively with the 'Metro' interface (not that I use it often, but there are a few quirks I've found useful).
Someone mentioned the 'drag and drop' nature of Metro when being used in Multiple monitor setups (that is, if you have a 'metro-app' (if that is the term) up, by clicking and holding the mouse where traditionally the 'title bar' would be, you can switch it between screens (be aware that it'll relocate the entirety of the 'Metro interface' to recurr on that monitor.
Also, to 'close' a metro app (without Alt-F4ing) simply 'grab' where the title bar would be and drag the app to the bottom of the screen. (and then there's the 'right-click' for more options in any 'Metro-app'.)
Other Metro features I've noticed is you can easily 'switch apps' by 'throwing' the mouse cursor into the top right corner of the screen and clicking (aim high, because if you've got a multiple panel desktop setup, you'll simply scroll to the next screen).
Similarly once you find that little gem, you can 'flick' to the top right, and then bring the cursor down to show an 'interactive' App-switching interface.
One 'quirk' I've noticed is that there isn't a straight forward way to 'shut down' in Win8.
The two quickest ways I've found are straight-up 'Alt-F4'ing once all apps are closed (or you 'select the desktop' before doing so);
and the other is to 'lock' the screen (WIN+L) and then select 'shutdown' from there.
There are a lot of Win8 haters ITT, whilst for the most part I can't say I'm stoked at having a 'touch screen interface' jammed down my throat where I'd prefer a more conventional desktop approach, if everyone stopped crying about what MS considers 'progress' and just passed on info about how to use the interface we could all move on.
The sad part is that I think MS have done a stellar job (for a change) at correcting the screwups they've had previously by creating 10 'Windows products' where you only really need 1 (ok, in this case they still have '4' (pro and non-pro, x32 and x64) but there's no more 'Windows mobile' which has gotta be a good thing right?). I'm not fond of MS' retail packaging options or the concept of even remotely trying to use a 'touch screen interface in a desktop setting'.
I kind of envisage that last part as a pseudo 'Minority Report' type way, sitting at my desk and swiping furiously at the 24" monitors I have ~1 metre away from me on my desk looking like more of a 'window licker' than a 'windows user'.
I'm LOVING how quick Win8 is, and both the file transfer and task manager interfaces have had an EPIC overhaul!
