No it isn't completely false. I have the i7 and the 512 of VRAM, and I'm able to play Star Trek Online in the native resolution with everything turned on high (8x anti aliasing!) except for shadows that are turned on low. It isn't silky smooth but its more than playable. Anyways, the Macbook Pro gets so hot while playing I can't have it on my lap without it being highly uncomfortable. Even with pants (as opposed to shorts). I often have to put a pillow under it, which actually props it up a good bit for more air circ, and solves the heat problem.
I've actually found that STO is actually easier to play on a laptop thanks to the proximity of the trackpad to the keyboard. I can have both hands on the keyboard while using my thumbs for the trackpad. I've become so spoiled I actually can't play using a regular keyboard/mouse setup, as this particular game requires constant attention to both the keyboard and trackpad/mouse to be played anywhere close to competitively.
