Weird, On my netbook while in the college building, I will run MAYA and photoshop cs3 at the same time while using firefox (I can create and edit 3d objects but I cant render as it is too slow to do it in a reasonable amount of time)
The good thing is that I can simply launch my vnc client then transfer over the project files to my main PC then have mental ray render it there.
While the ad is not accurate, it will help sell a product to someone who has no idea about computer hardware.
From my experience, if you explain how multithreading works and also how single threaded apps can benefit from having more cores but also why depending on the budget, in some cases it may be better to go with a fast dual core instead of a quad core with 4 slow cores, especially when gaming, they tend to get lost very quickly. (this was a while back when things when quad cores were just beginning to get popular)
so sometimes you have to give dumbed down answers and as a result, you also lose accuracy
