I'm happy because now I can start a proper farm. Wheat for taming and breeding the animals, then using the excess to make breads. Cows and chickens provide milk and eggs, and some sugar cane and you have a full-fledged bakery capable of churning out mouth-watering cakes.

Magma cream... and a lot of new useless items!!! Yeah!! Seriously they should add USEFUL things, and fix the damn bugs, and also put the sky limit higher... that would make me happier than having Spider Eye, Blaze Powder and other things that nobody knows their purpose...
Holy crap, ender pearls are perfect!! They're not too overpowered, because they can only teleport you as far as you can throw, but they're perfect for getting out of holes when you don't have blocks or ladders.
