The new MacBookPro lets you "right click" if you click on the trackpad button while resting two fingers on the trackpad. So, if you have two fingers on your trackpad for, say, scrolling up, down and sideways, all you need to do is press the button for right click. it is very cool and easy to use with just one hand.
For it to work, you have to enable this function in System Preferences : Keyboards and Mice.
What I do hate is the second ENTER key, that serves absolutely no purpose, as it is just two keys away from the actual enter key. I would love for Apple to let me map something else to that key, like they already do let you remap your CTRL, OPTION and COMMAND keys. If i could remap that, i would put a Forward Delete button there. It would be great for word processing, especially because it would make it easier to use key combinations to forward delete a whole word, which now requires a crazy 3 key combination that is not very practical.
