So I need a laptop that is light enough and powerful enough. The portability of the laptop is very important since I spend alot of times on commuting. I am on the train for about 2hrs per day and my university is pretty big, so I have to move from place to place. My individual research has made me think about purchasing the Dell XPS 15 i7...I also like the alienware 13 r3 .... alienware 15 r3 seems really heavy. The MSI ge62 looks good aswell however I do like the mobility of the xps. So what do you think, which is the best for the price. Any other laptops I should consider?
