1520 vs 1521

Can someone tell me the difference in these two? I've been wondering for quite some time now.

 

processor options mostly.

1520 has intel. 1521 has amd. i dont know, but im pretty sure thats the only difference, but obviously some other differences may occur because of the different processors, like battery life, heat, ect, ect.

 

The bluetooth is different I believe. The 1520 has a 355 card and the 1521 has a 350 card

The 1521 uses a cheaper, slower, and more battery draining AMD line of CPUs, and it uses the Radeon 1270 low-end graphics. But hey, it's a decent laptop capable of general tasks in Vista, for the right price.
