lolinc: Tbh, these days, I'd probably just go with an Apple. . . Macbook Pro or something. Yah, probably closed-system form-factor, but Apple's usually way ahead of the game

Right. . . thermal barriers: tbh, the only laptop I've ever owned that had absolutely fantastic thermal regulation. . . don't laugh. . . was a Gateway M350WYN; you could see the big-ass, serious copper heat-sinks from the vent in the back. . . two big-ass fans at the base. Also, and this was not particular to this model, the power supply was external mid-way down the cord, and. . . had its own sink and fan. I actually played games on this thing in a truck-camper, and it was around 90 deg. F, and over 90% humidity. . . in dynamic mode. This thing also had outstanding peripheral options. . . just a stellar machine. Cons: you could hear this thing running a mile away (dynamic), and all that copper made it relatively heavy. But hey, it was a laptop with dual exhaust, and I loved it. I still use it for some legacy titles and emulation.
A lot of thermal issues could be resolved if they just kept the power-supply external: it was practical, and it wasn't all that clunky at all. Secondly, these goofy, fashionable form-factors; everyone wants an anorexic laptop on which to play Skyrim. . . or whatever.
And so, heat isssues result in chip throttling, and consequently performance. But, like I said, these days, I'd still go with the MacPro, if I were going to buy a laptop at all, the alternatives just seem dismal. Hell, you can do more on a tablet or iPad than some of these notebooks/laptops. . . ridiculous. We used ours (2012 Mac, boot-camped) for mostly practical reasons, when we traveled alot. . . played movies well, ran Sacred, D2, NWN, TQ without issues, but those weren't particularly demanding programmes. . . except Sacred 2 with that Invidia physx bloat. The last "gaming" laptop I had was a Toshiba, constantly over-heated just playing Sacred 2. Except for the old Gateway, I'm done with laptops; they just can't handle some of the more demanding software that desktops can. Again, manufacturing practical, performance-based form-factors could easily change that. . . that's my opinion anyway.
