June 16, 2012, 7:48 AM — You have questions, oh so many questions, about the new Retina MacBook Pro. You had so many questions that they couldn’t all be covered in Jason Snell’s hands-on article. So Jason gracefully handed the Retina MacBook Pro over to me so I can address more of your questions, asked via Twitter (through our @macworld account).
I’ve spent some time with the Retina MacBook Pro, and I’ve answered some of the more common questions here. This is a small sample, and there’s no doubt that there are even more questions out there. So post them in the comments below or ask me via Twitter @pinatubo2000. I’ll try to address them in our full review of Apple’s latest laptop.

From @pcweenies: Temperature-wise, how hot does the new MBP get?
I don’t have an exact temperature, so I’ll try to give my best subjective observation. As a reference point, I’m using a 17-inch MacBook Pro on my lap. When running the installer for Diablo III, the 17-inch laptop gets warm enough start the fans. I have to take the laptop off my lap and rest it on a table.
The Retina MacBook Pro, while running the Diablo III installer, warmed up, but not enough to make me uncomfortable while it rested in my lap. The heat was from the center of the bottom of the laptop, and it didn’t seem to radiate beyond that. The fans did not kick in.
I watched several YouTube videos and iTunes movie trailers, all streaming 720p over the Internet. The laptop got a bit warmer than when I installed Diablo III, but not hot enough for me to need to move the laptop off my lap. I wasn't able to trigger the fans while doing this, and the videos ran smoothly.
I also used Handbrake to convert a movie file for my iPhone—the Retina MacBook Pro doesn't have a optical drive and I didn't try ripping a DVD or CD using an external drive. The file conversion took less than 5 minutes, during which time the fans did not run, and the laptop did not noticebly heat up.
These are subjective experiences. Macworld Lab will take a look at heat issues with the Retina MacBook Pro, using equipment to measure the heat generated from the laptop.
From @curtisbridges: Any fan noise when pushed to its limits (CPU and gnu)?
