Right now the 80GB Windows partition just doesn't seem good for games space-wise, and the weight of the MBP seems just a little too heavy. I don't even use the Retina Display too much. I hook it up to a playstation monitor. I think I would like a lighter laptop and dedicated gaming pc. The Alienware I'm looking at has a core i5 as opposed to the rMBP's i7. I'm hoping if I get $1900 for the rMBP, I can get both an air and a $700 Alienware. Don't have the money saved up to just get the desktop, and don't foresee this possible without selling because money has to go toward destination weddings in the next year (first world problem I know). Someone told me to just get a 1TB external drive and stick with what I have, which is another (probably smarter) option. The person told me that would be better if I want to game on the go. I may just suck up my first world problem and do that. What would you do in this situation? MBA and Alienware, or the smarter more practical option?
