In response to 2), I use a friends mac and think "wtf were they thinking" quite often. Default browser can't fullscreen/kiosk mode? Resize from only one corner, not any border? Heavy reliance on keystrokes with low discoverability?
Apple makes a nice bit of kit, but please, can we stop with pretending they've got it perfect?

Neither is true in 10.7.
Heavy reliance on keystrokes with low discoverability?
For the most part, keystrokes follow similar patterns from application to application. There are inconsistencies (some applications use ctrl-tab to switch tabs, some use ctrl-pgup/pgdn) but for the most part it's self-consistent. (There are some nice power user tweaks, such as a subset of Emacs keystrokes available for navigation in text boxes, but they're not critical.)
It depends where you are coming from I suppose. Kiosk mode until recently didn't really fit in with the Mac (going way back to System 1.0 days) work flow, but when Apple integrated multiple desktop into OS X, it shifted the workflow enough to allow for kiosked windows to inhabit their own 'space'. It's worth checking out as it's quite an elegant solution. I, and I think the vast majority of Mac users would agree on the resizing point and thankfully it has been addressed, but it's worth remembering that the original idea behind one location to resize windows was overall simplicity. Whether or not simplicity was achieved however is an entirely different thing, and I imagine that we'd agree that it wasn't! WRT to short cut keys, they have always be displayed in the menu. Since the menu bar is the primary way that many functions are initially accessed, the idea is that eventually the users will learn them through exposure, which in fact is exactly the same way that most desktop UI educate users. The Wiki entry on the command key make for "intersting" (well, to us geeks mainly!) reading. http://en.wikipedia.org/wiki/Command_key#The_origin_of_.22.E...
your first two complaints are actually fixed in Lion- and I have to disagree with your third. There's nothing in OS X you need to use a keyboard shortcut to do, and it's easy to find the shortcut for a menu item- it's displayed on the right side of the menu.
