a bong LOL for u TS....why would u want to buy a macbook air but in the inside still a windows?is it just for a show off thingy?btw,u can install a windows inside,but not 100%.u can't delete the osx.bootcamp will allow u to install windows in a new partition.

@tpl
ouh.....if that's the case...if that's my wife,i would do the same,lah....so,the best way is,just put as large as possible partition space for your windows using the bootcamp.it's not that hard to install windows btw,just follow the steps from the bootcamp assistant.btw,u still have dual boot in the end.so,just boot the windows lah.
