Planning to get my first Macbook. I'm currently torn between the 13" Pro and 13" Air. Both will be upgraded to 8GB RAM. Did a fair bit of reading/research. Based on benchmarks, the 13" Pro (2.9Ghz) is about 28% faster (Geekbench Benchmarks: 8590 for the 13" Pro and 6670 for the 13" Air). I will be doing engineering in uni. but I think the Air's performance will suffice for most software needs. And I can cope with a slower speed for the occasional use of such software cos at most i'll do the module for a semester and i wont use it again. But more importantly is running Windows on Mac. Did some reading on the difference between Bootcamp and Parallels. The HDD/SSD space difference between the two is the one that will decide which I will be getting. Bootcamp I will need to do a partition on my hard disk. Assuming I get a 13" Air with 256GB SSD, the usable space will probably be lower by about 10-20GB? Not sure of the exact amount cos I've never had a Mac and unsure how much space OSX takes up. Given that I will only use Windows 10% of the time, how much SSD space will be needed to install Windows and maybe a few programs? Would 50GB be sufficient? That will only leave me with at least 150GB SSD of free space on OSX. And partitions cant be increased/decreased without having to re-do the entire boot camp setup right? RAM - While I understand that HDD space will be partitioned? What about RAM. Will they be partitioned? Or will I get to fully utilize 8GB when I'm using OSX, and fully utilize 8GB when I'm using Windows. I notice that for Parallels they assign the amount of RAM. Parallels Based on youtube videos I've seen, it's like running Windows in OSX like an app. When installing the Windows via Parallels, we are asked to assign the RAM. If 2GB is assigned from a the 8GB ram, will that be permanent? Or if I'm not running parallels the full 8GB will be used by OSX and when I open Windows via Parallels only then will 2GB be assigned for separate use? ---------------------------------------------------------- In a nutshell, I'm deciding between the 13" Air and 13" Pro on its abilities to comfortably support Windows (either via Bootcamp or Parallel). And of course, I will need a Superdrive to install Windows on the Air but I just found a workaround to install via a USB flash drive. Thanks in advanced.
