Thanks for answer guys.
I haven't notice the longest battery on the toshiba, so that's a plus for me.
I'm very concern about video performance. I have read that notebookcheck review about ATI 6650M but when I get to Tom's Hardware to see the hierarchy I notice that the Nvidia GT 540M was 16 levels below the top while the ATI 6650M was only 11, matchet by a Nvidia 9800M... Maybe I'm wrong about this, if so, please correct me.
I was so tempted to Toshiba because of Nvidia enhancements and performance but Toshiba it's having bad comments on certain laptops (bad sound, cracking, sound stop working, touch pad not working or stop working hafter a while, etc), so I'm affraid this may happend with this model. Lenovo it's a robust and rough brand, I've seen laptops endure use and abuse so that made me considere it. On the other hand, Toshiba it's a Japanese industry leader, they have good support, no so much bloat ware...
I saw the Samsung and, honestly, I'm not confortable buying a laptop from Samsung. A monitor?, a phone?, hell yeah!, but a laptop???. Besides' it's too expensive!, it doesn't have the same amount of RAM nor HD space...
So, what else can you tell me about ATI HD 6650M vs. Nvidia GT 540M so I can make a choice?
