Then you want i5. I just returned my lenovo i3 (8gb-500gb) and exchanged it for a samsung i5 (8gb-1tb). The i5 your looking at has a faster processor, more ram, bigger hardrive.
Basically theres gonna be a major difference in speed. If you don't care about speed, stick with the i3. Btw I paid $649 for my i5 and it has a better processor than your dell.
Maybe keep looking...
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
