Dell Inspiron 15R (5520) 15.6" Core i5 Ivy Bridge Laptop $550
48 WHr 6-cell Lithium Ion Battery
If the battery WHr ratings are all equal the 5520 Inspiron 15R should have the longest lasting battery life.
No gaming at all.
I cannot buy this model but the Inspiron 15 N5050.
I guess I have to choose between a
Toshiba Satellite L750-11W Core i3 2310M 2.1GHz 6GB 500GB HDD GeForce GT 525M 1GB Silver and a DELL Inspiron 15 N5050 Core i5 2430M 2.4GHz 4GB 500GB HDD HD 3000 .
