The funny thing is even a tablet or smaller phablet would be more viable than a laptop, if they could give it good battery life, and make it powerful enough to be able to handle PC games at 30 or 60fps. Assuming the Steamboy is legit, it's said to handle the majority of steam PC games.
If visuals take a hit, then it's a fine, as long as the framerate is smooth. 60fps might be asking for too much on my end i guess. 30fps will be doable.
However, hows the battery life? preferably on low settings?
I'd normally agree with you due to me being an FPS maniac (I like to maintain >60fps at all times, 120 if possible) But lets be honest, if you plan to play EVERY PC game at 60fps, then the graphics are reaaally gonna have to take a hit.
And if you're OK with crap looking games, then you're probably doing it wrong.
I have the i5 Surface Pro 3 with 4gb ram and it plays Dota 2 and Civ 5 at 2160x1440 at around 30 fps with the fancier effects off. Haven't tried something like BF4 or Metro: LL on it yet. Haven't used a lower res either.
