Hello everyone, I will be buying a new MBA 13" soon. Here in India only two options to choose between i5/4/128 and i5/4/256. What model should i choose? though Money is no constraint and I have external hard disks too. 1.Will 128 SSD be enough to run windows 8 with onboard 4Gb RAM? 2.Is there any brand and speed differences between 128 and 256 models? Yeah i know 256 is faster than 128 but could we see any real world differences? Thanks.
