Yes, the new MacBook Pro with Retina Display has RAM that is soldered in. You can't upgrade, and have to buy from Apple. The new MacBooks also have a new magnetic plug in that won't work with the old cords. Mac always does this (changes something that requires you to pop another 20-40 dollars for an ‘adapter’), an it is really becoming irritating. Having said that, I've seen the new MacBook Pro and the display is quite amazing.
I have had a Macbook Pro for over two years and never had a problem with it. My I-Phone is totally fine and my I-Pad is great when on vacation and other times. I have ZERO problems with Apple. Too bad more companies can’t be like this success story.
I’ve had my MacBook Pro for 2 1/2 years now. Not a lick of trouble. The battery life is amazing - almost 7 hours for basic work (not on internet, etc.).
You can replace the battery yourself.
