Toshiba is cheaper.
That is a mispront with the i7-740M it should be 1.73 but can be overclocked to 2.93.
The Toshiba uses the i5 which is a dual core 4 thread processor while the i7 is a quad core 8 thread processor. The clock speed of the i5 is from 2.53 to 2.8 while the i7 is 1.73 to 2.93. The i5 has sharing graphics between the discrete and intergrated graphics card while the i7 just uses the discrete card.
Bottomline is the i7 is faster and more powerfull but with that power it uses more resources and runs hotter. Depending on how you use the system those resources may be wasted and using battery time and diminishing the life of the laptop.
If you want the i7 wait for the Sandy Bridge (2nd generation i processor) because it will share between the discrete and integrated graphics card as the current i5 460 does. It also conserves power usage of components that aren't being used giving you less heat (longer life of the laptop) and better battery life.
hey guys , i'm so confused between these two laptops
