Apple Macbook Air, 13-inch, Mid 2011, i7, 250GB, Mint Condition in Farrer Road, North Singapore for sale

Hi all
I'm selling a 13" Mid 2011 Macbook Air. It is in flawless condition and has only seen very light use (I work on an iMac - this was just for meetings.) The specs are as follows: -
CPU: Intel i7 1.8Ghz with turbo boost
RAM: 4GB
Storage: 250GB SSD
Graphics: Intel HD 3000
It was the absolute top of the line option when I bought it, and runs Photoshop, Premiere, and Illustrator CC 2014 with ease. I can't imagine that a "newer" macbook air will run day-to-day software better than this can.
I am looking for SGD700 ONCO. Can meet at Raffles Place, Telok Ayer, or Farrer Road MRT.
Comes with power supply. Please be aware that as this is a UK model the keyboard layout may be minutely different to a Singaporean one - the only difference I'm aware of is that '#' is alt-3 instead of shift-3, though you can probably change that in settings!
Thanks
