<p>I will be majoring in Aeronautical and Astronautical Engineering at Purdue and am in the process of researching computers. I have a budget of $1600. I'm not into gaming. I am very computer-illiterate!</p>
<p>I have narrowed down my choices between a Lenova T420s and and a Dell Latitude E6420.
Is there any advantage of one over the other? Any others I should consider? </p>
<p>Also, with regard to processors:
The Lenova T420s has a Intel Core i5-2520M Processor (2.5GHz, 3MB L3, 1333MHz DDR3)
The Dell Latitude E6420 has a 2nd Generation Intel® Core i7 Processor</p>
<p>Both of these are Sandy Bridge, right? Is one better than the other?</p>
<p>Thank you!</p>
