Here's a short snip:
The user interface is often a deciding factor in the user's enjoyment of a title and Turbine hasn't been asleep at the wheel in this department. The basic layout should be familiar to most players by now, as it appears to have been heavily influenced by World of Warcraft. Your typical portrait and status bars reside in the upper left, mini-map at the upper right, chat interface on the lower left, and various and assorted icons at the bottom. One nice improvement is the reactive hotbars. Instead of displaying row upon row of icons (though this is an option), additional rows are only shown when pressing the corresponding hotkey. For example, if you had an attack bound to Ctrl+1, the Ctrl hotbar only appears when the key is depressed.
