Hi everyone! Pretty new on this forum, (at least when it comes to posting), but i need some help now, and I'm not that good at Macs and OS X yet. I'm considering buying a rMBP, even though I'm mainly a Windows guy, so I'm gonna install Windows 8 even though that's like blasphemy for some of the jobelievers in here. (I'm not that fond of Windows 8 either, but i might as well use the newest version and get used to it.) I don't really care about that, it's for practicality. And I was just wondering if 256gb is going to cut it for me? How much of that is free out of the box? And this might seem stupid, but is OS X able to run for example photo shop off a external hard drive? As I will need a external hd for a lot of applications and some games. I'm going for a 2,6/16/256 version. The hw should cut it for me for a couple of years. The ssd size is probably my biggest issue, as one step up is going to cost me a little over 700 usd here in Norway, and I simply cannot justify that price. I've tested a lot of rMBP's with lag, and a lot without. And I believe that the hw itself has nothing to do with it, as the 650 is more than capable of pushing that kind of resolution, so I'm just wondering if people have been able to find a solution to the problem? Lagging while doing simple everyday tasks isn't ok on a $3900 machine. Also, does anyone know the rate of Samsung/LG screens on these machines? I'm really hoping for a Samsung, as they in general make the best screens out there, at least when it comes to lcd and oled. In case anyone is wondering what my option is, it's a Asus U500VZ, which looks like a pretty impressive piece og machinery. Thanks in advance for any helpful answers!
