Despite these improvements, the computer still isn't good enough for me to recommend.
The 13-inch Retina now starts at $1,499 down from $1,699.
While price point was definitely a problem with the 13-inch Retina, the 15-inch is still a better buy.
The 15-inch gets you a higher resolution screen (2880x1800 versus the 13-inch's 2560x1600) with more real estate and a quad-core processor. MacBook Pros aren't consumer-first computers, and I'm not sure why a professional would want weaker power, with a 2-inch smaller body.
If you're a professional you can shell out the extra dough (starting at $2,199) for the 15-inch's quad-core processor, discrete graphics, and larger screen. If you're a consumer go with 13-inch MacBook Air, you'll be fine in terms of speed, trust me. You'll also save $300 that can be used to up your RAM (one of the most important computer specs).
