Guys, I REALLY want the high-res 15". Been calling everywhere but literally none of them have it in store. I would've much preferred to get in in store so I can have it straight away, but I guess my only choice is to order it online..? If I DO order it online, are there any disadvantages [obviously other than the wait of delivery] compared to buying in-store, e.g. more inconvenience to get it fixed/returned and stuff etc? Thanks - if there ARE more disadvantages, I might just buy the standard res. Opinions?
