Let me rebuttle these "issues":
The standard File/Edit/View menu is completely separated from each window and appears on the top bar, like a Mac. This is unusual for Windows users. Worse yet, the File/Edit/View menu is actually hidden until you move your mouse up to the bar, and then it appears. This is just unnecessarily confusing.
Personally I prefer them in the menu bar as it's a space saver but it's not for everyone, hence the option.
The window management buttons (close, minimize, and maximize) appear at the top-left side of each window instead of the top-right side. This is more like Mac OS X than Windows. There used to be a hidden option to move these buttons back to the right side, but it no longer works.
You can't move them in UNITY (in Gnome they are on the right by default) because in Unity when you maximize a program it's close buttons appear in the menu bar.
The Unity desktop features a sort of dock, known as a launcher, that displays shortcuts to your applications and to running applications. You can’t get a more traditional taskbar, if you prefer that, as you can on Windows.
It works the same as Windows 7 and 8's taskbar except it's pinned to the left as opposed to the bottom.
The application launcher is rather confusing. Rather than being an easy pop-up menu with a list of useful shortcuts, it’s a full-screen search interface by default. To actually view a list of installed applications, you have to click the Ubuntu shortcut and select the little Applications view icon at the bottom of the screen. You then need to click “See more results” next to your installed applications and you’ll get a full, alphabetized list of applications without any categories or other useful information. The so-called “dash” interface works best if you use it for search, and you’ll see Amazonsearch results if you do that. Other options you might expect to find in a “Start menu”-style menu appear in the indicator menus at the top-right corner of the screen.
Fair enough complaint. Although Lubuntu, Kbuntu, Xubuntu and other 'buntu use a more traditional start menu.
Like I said, I've tried Linux Mint multiple times and I've felt it's a fine experience. It isn't the most forward thinking desktop, as you implied by saying it looks like XP, but it runs fine and has a place. It just isn't for everyone and all the 'buntu guides that Tek Syndicate are making can be applied to Mint.
