Hi everyone first of all i'm not a native english speaker, so if you hate when someone makes mistakes in your language please don't be rude i´m learning. The thing is that im going to CS college and starts in 3 weeks, i didn't knew it starts that soon so i'm in hurry to choose a weapon, i was hoping for the haswell non retina MBpro get release, but maybe i wouldn´t be able to wait, so my candidates right now are (these are between my budget n' are officially sold by the manufacturer in my country): MBA 2013: Intel core i7, 8GB, 256GB, 13 in. Alienware 14: Intel core i7 (haswell quad core), 8GB, HDD 750GB/msata 32 GB, Nvidia gtx 765m 2gb gddr5, 14 in 1080p ips, Win 7. Dell Inspiron 15r: Intel core i7 (ivy-bridge dual core), 6GB, HDD 1TB/msata 32GB, AMD Redeon 8730m, 15 in touch 720p, Win 8. IF you don´t care about the details, just skip to the doubts section The facts: °The strong is the alienware, but the battery life (on extreme energy save mode= 3hr 30~50 min) it's gonna be an issue in classrooms (i type faster than handwritten so im expecting to take all my notes with the computer) and is the priciest. °The pretty is the MBA, looks so good and i can develop apps for my iOS devices but i could need more power (i've never owned a mac). °The friendly is the inspiron, it is between power n battery life, but with 15.6 in. is too big for the armchairs in class (the extra screen is always welcome when coding, but it will not fit in my actual messenger bag so i'll need to get a bigger one or a backpack) My Concerns: Alienware: I'm a gamer but i prefer to play on consoles, so alienware looks atracttive to me but not too much, anyway i think it's the one where i get the most for my money also it could be a good desktop replacement when retired, but the battery life is too limited n' i dont wanna look like a swank showoff typing on a alienware which is not meant to be a notebook. MBA: I like to write stuff specially when i can't sleep so the retro-iluminated comforty apple keyboard seems my best bet also i wanna try Mac OS X looks friendly for college n' coding, the whole Mac experience looks incredibly attractive, however the lack of a dGPU, small screen size n' resolution makes me feel i could regret it, and the price of a macbook pro with dGPU is too damn high. Inspiron: My counscience tells me that the inspiron suits my needs n' anything more could be just luxury n´comfort, no matter if i think that the inspiron looks ugly, bulky n' the touchscreen in a laptop is useless, n the fact that im paying a licence of a OS i don´t like (i'd rather get Win7 than 8) after all is my parents money and even when they offered me enough to afford the alienware doesn't mean i have to take it all. Doubts: To MBA owners: is the Air core i7 8GB enough to flawlesly run Visual studio 2012? would it run autoCAD for some light 3D drawings? how does it feels to develop for iOS in the 13 in Air? To anyone who recently switched from win to mac: The OS n' design really worth to get less capable hardware n better user experience for the money? To hardware experts: Do you think that intel 14 nm broadwell processors will be released before 2015? Because is way better if i get a cheap laptop, save money and wait just year1/2 for the generational jump from 22 nm to 14 nm (broadwell and skylake) with ddr4 to get an expensive pretty machine like the MBA, if that jump is that close better wait am i right? To Mac experts Assuming i'll take care of my MBA like it was made in gold how many years being a smooth well performance machine will last? More or less which date apple use to release new products? (i know is september or octuber but im not sure) Assuming you have to choose "not considering any of my personal concerns and needs" which one would you get and why?
