I bought this laptop 6 years back, but still I'm working with inspiron 15 inch 1545. I would like to specify some of features about it
Hardware: excellent hardware design and user-friendly. Battery capacity about 4 hours without charging. 15 inch looks little bigger and weighter.
Performance: 4 gb ram gives fast performance and have 512 mb graphics card I can play bigger game in my laptop. 320 gp hard disk enough to store my all data's.
Dell offers original windows OS so I can update OS any time. Have a read and writeable drive.
Overall I love my laptop inspiron 15 1545
