Great machine... which I have to send back.

Laptop is great. It arrived quickly and I was very happy with the performance... then I ran a benchmark test that told me, instead of the 16GB of RAM I'd bought, the machine was running 8GB. Double-checked and confirmed through the system information and got in touch with AO who have suggested I get in touch with Asus and send it to them for some tests. The last laptop I sent to Asus for a minor fault on the keyboard was never returned so I'm not hugely excited by the prospect. May have to request a refund and begrudgingly go down the Apple route instead.
