Alright everyone, I am looking for a durable ultra portable but fully capable laptop, I am not interested in tablets. Battery life is very important to me, as is speed and efficiency of the machine in general.I will be using Windows 8.1 64bit on either machine I buy, I am currently looking at the Retina 2015 13" Macbook Pro with 2.9 I5, 16GB of ram, Intel Iris 6000 and 512gb SSD, or the Dell XPS 13 which only has a 2.7 I5, 8GB of ram MAX, Intel 5500HD and 256GB SSD. The battery life on the MBP is reportedly generally over 10 hours, while the dell is hovering somewhere between 7-8 hours. Money is not the issue here, and I am not a Mac fanboy by any stretch if I buy this MBP it'll be the only apple product I own. I am looking at this purely from a hardware standpoint, I am currently leaning toward the Mac because the specs are just so much better, and before anyone asks the ram isn't really super important I doubt I will ever use 16GB but I figure if I'm buying a laptop which has soldered ram chips I'm just going to get the max the machine can offer so that It never becomes an issue in the future. Also I may occasionally play World of Warcraft on the machine though not often, which machine would handle that better as well? Thanks everyone
