Screen Size 13.3 inches
Screen Resolution 1440 x 900
Processor 1.3 GHz Intel Core i5
RAM 4 GB DDR3-SDRAM
Memory Speed 1600 MHz
Hard Drive 128 GB
Graphics Coprocessor Intel HD Graphics 5000
Wireless Type 802.11A, 802.11B, 802.11G, 802.11n
Number of USB 3.0 Ports 2
This is my first Apple computer and feel it is a nice compliment to my iPhone 5. Certainly a better upgrade than my Toshiba A505-S6965 which will turn 5 years old in August. Much lighter, better battery life, no overheating/loud fan running, and just a lot smoother than my Toshiba running Windows 7. I was always turned off from MacBooks because of the price but glad I made the switch.
