[QUOTE="wirelessmacuser, post: 1006703, member: 136479"] In my experience with my two month old 15" MBP, it seems that unibody MBP's run warmer than a comparable ThinkPad for example. I use both and find the ThinkPad can go for hours on flash intensive sites and run cool. Not even warm. It has to do with better thermal management of the ThinkPad, and more efficient fans (which are not needed as much as in the mac). . Also one must remember that the aluminum body of the mac conducts and retains heat. A high quality composite carbon fiber reinforced plastic housing (CFRP) like ThinkPads are made from is very good at dissipating heat. Thus the palm rest and body is much cooler. Also the thickness of my ThinkPad is 1.2" vs 1.0" of my MBP. While that's not much, it makes room for air to circulate through the case so I don't feel hot air flowing up out of the keyboard as I do on my MacBook Pro. . So... They are just different. A Mac is designed to run hot and will recover even if it gets so hot it shuts down. I've had a friend with the first generation MacBook Pro have that issue, yet the computer survives even when the screen goes black. Nothing to be concerned about unless it bothers you. Many people make the mistake of comparing a PC based Laptop to a Mac. That's not relevant as they are two completely different machines with two totally different Operating systems. If you go to forums for mainstream laptops, they _never_ talk about flash because its just never a problem. That's why its so popular and all over the web. Eventually at some point in the future the emerging technology known as HTML5 will begin replacing flash.
