not at all.. two finger scrolling.. no
But, I would say that the extra VRAM may prove to be helpful in the future..
Do this, get the 1.33 like me, add a gig stick of ram for 120 bucks @ newegg and get a 5400 rpm hd... it'll smoke a stock 512RAM/4800 rpm HD... leaps and bounds
I also have a 1.5 with 768 ram that I'm basing this off..
