Cheaper, yes compared to the Indian pricing. Head to the Macstore at the Ibn Battuta Mall on the Sheikh Zayed Road, Dubai. The Macstore is run by ABM, the official retailer for Macs in the UAE. Several Carrefour outlets also retail the entire Mac lineup save the displays. Worth a shot IMO.
Warranty shouldn't be a concern since it has the international warranty.
Opps, Im too late to post this info. Apple Mac Store will be officially opening in Dubai soon (first time in the history of the world!). Prices should be cheaper at that time (my speculation).
Got the 11 inch air with 128 gb ssd for 5499 aed. 64 gb ssd was for 4499 aed. The other shop in the mall which had it at the same price was sharafDG. They had arabic with English keyboard or only English keyboard I chose the latter.
