A:Answer As someone who's owned both, I would say if you're not a huge high gfx gamer (on your laptop that is), then I would keep the $200 and get the Acer, which is the one I have now.
The ThinkPad is awesome though, and if you don't care about price, then I would get the ThinkPad. ThinkPad is better spec wise and also it comes with a stylus!
But I wanted to save $ and tried out both of them, but I found that I never play serious games on my laptop and that the Acer is fast so I had no complaints about it.
