I'm testing my uncle's new MacBook Pro base model, as my one with the upgraded specs hasn't been shipped yet. And man this thing is so fast and responsive. Looking up dictionary definitions lightning quick. Loading up webpages is lightning quick. I have a 4470R PC with a Samsung 850 and 16gb ram running Windows, and it scores much higher in CPU than this laptop. And I never thought websites could load any faster, but I was 100% wrong. Using the same Wifi, everything on the internet is loading super fast. I definitely think the SSD drives in these MacBooks make all the difference. Thats the only thing that is faster than any of my other computers. These SSD's in the MacBooks are stupidly fast, and they definitely make a difference, even just loading pages. Very very impressed, that's all I can say really. And the keyboard is decent too.
