One thing I wanted to separate from the paragraphs above is … my gratitude to Apple Inc. My Macbook suddenly experienced a flood of problems. I took it, while on my business trip, to an Apple service center and I got it repaired within 48 hours. So good-bye cracked plastic case! Bye-bye deformed battery! And hello looking like new Mac! So, thank you Apple Inc. and the authorized service center for being reliable, fast and understanding! You rock, guys!
