"I struggled trying to decide if I should buy this laptop or Apple's Pro notebook. While the Apple was significantly cheaper it lacks the speed and sophistication of the WS701. First off, the Lenovo is quad-core and has the fastest chip available. I am amazed at how fast it is able to run complex programs such as photoshop or even to just rotate a photo in a simple image viewer. The real deal breaker was Lenovo's video output which allows me to achieve resolutions on an external monitor beyond anything that the Apple can. This is important in my photo editing work. Also, the screen is calibrated to show all of the Adobe profile colors. Apple's doesn't. I and friends are amazed at how stunning the color rendition is. My Spyder Calibrator confirmed the factory calibration. A bonus feature is the USB 3 outputs. I recently bought an external drive capable of using USB-3 and it is radically faster that what I can achieve with USB 2. I haven't tested it yet buy I believe I am able to write to this external drive in a shorter time than to the internal hard drive. I would buy this laptop again and recommend it to colleagues. It might cost more than the Apple, but it is definitely worth it."
