First impression with this external harddisc by Western Digital that very suit to the MacAir users. It’s seem like it made for each other.

[later added] I find this device available at iStudio Nawamin City branch. It’s name is “My Passport Essential“. This MacAir like color model available in 2 sizes, 320 GB at 1,650 THB and 500 GB at 2,150 THB. Hope this info useful for who interest in it. 🙂
