Uhh... what? Command + Esc is similar to Ctrl + Alt + Del. Lock/login is as simple as checking a box in System Preferences. I also don't see how you have issues with accessing files on a network under OS X. They're all there and easy to find under the nice "Shared" list. In fact, I often take my Macbook Pro into work and use it on the all-Windows network there without any problems. File paths can be found if you click "get info" on a folder.
1. Command+ESC on my MacBook Pro launches something called "Front Row". So much for consistency?
2. The way Mac handles networked drives isn't simply "hey I can connect to it!". I've explained this before. You failed to read in further detail. Inability to rename network drive shortcut on my desktop. Having to add the drives to a login script to have them reconnect everytime. Then when they connect they open the folder - which means I have 5 folders pop open every freaking time I login. Not to mention if I simply create a SMB drive alias it takes forever to connect. Windows connects like it's a local HardDrive. For some reason Mac is painfully slow to connect. In Windows 7, if the drive isn't available, it simply Xs out the drive and I cannot connect. But with my MacBook Pro, it ask for the login information for every single drive it cannot find and I have to cancel out of it. It just seems like a massive pain in the ass on a Mac to use network storage. Not to mention if I search for the answer I get 20 different ways of doing it involving Apple scripts, Automator, Plugins and all sorts of BS. It's not simple to do it RIGHT. It's always a "work around" or something that doesn't seem to just WORK. Example:

3. Again, the simplicity of Windows having a toolbar that shows the full path like a URL is far simpler to use than having to use a key stroke or right click, get info and then having to cut or paste. If I need to cut and paste the path to 10 different files, Mac becomes a real pain in the ass.
Then there are thinks like the inability for it to use AVCHD files without a full file structure, yet Adobe can use just the file. I run into things like that on the Mac where it seems like Apple just intentionally makes it a pain in the ass for users.
I love the Mac, I really do, but it's frustrating sometimes.
