    Does your rMBP run cool enough to use on your lap for extended periods without getting warm legs?

    Everybody, for the poll we are talking web browsing, watching vids etc. Not encoding a video or playing a 3D game etc

    Its going to get warm, but how warm it gets depends on what you're doing.

    Using a CPU intensive task means it may get too hot for your lap, surfing the web, it should be ok.

    Also consider a lap desk, they will protect your legs from the warmth and also elevate the laptop to be a bit easier to use.

    Of course it gets hot. It wasn't designed to use it on your lap. It's not a laptop, it's a notebook.

    Forcing it to use the integrated graphics helps keep the temperature and fan noise down.

    I saw that it was running warm and loud running XBMC on discrete graphics. Since I knew they weren’t needed, I turn them off with gfxCardStatus.

    Based on my experience with the 2013 MBA, I expect the Haswell models will run cool enough to use on the lap. For the MBA you can even run it with bare legs.

    I think notebook is just the marketing jargon they invented for "we just can't get these things to run cool yet, please don't blame us when you burn your lap."

    People want to be able to use these things on their laps, its just a question of when the heat produced and cooling provided allow this to happen.

    Rather then a marketing term, its a realization that these modern CPUs run hot and there's little they can do to cool them in such a small enclosure.

    I use mine on my lap, but it does get warm - I avoid using it when I'm wearing shorts, I need pants to help insulate my legs. I also mentioned the lap desk as a solution and I found that works best.

    It's highly variable what people consider "cool," I know people tat think a 15" MBP isn't portable, and people that think they're computer being at 90 will melt it. That said I've never had a problem using my computer on my lap for normal use.

    Yep I use a zalman 3000 cooler and my 17" early 2011 MBP lives on it. There is no way I could use it on my lap without it. However I used someones 2.3ghz rMBP the other day and for web browsing and videos it was fine on my lap for 10mins or so. (It was in a speck case though not sure if that gave it the edge). Was interested to hear the general feeling on this.

    Normally there's no problem. If I stream HD video for a while then the bottom can get uncomfortably warm.

    That's an important edit.

    With the edit, yes my rMBP is cool enough for comfy lap usage.

    But if I start doing heavy-duty stuff for a while (in my case, virtual machines) and it's a warm day, I'll want to use a laptop pad or spin up the fans using SMCFanControl.
