Well I'm doing reformatting and configuring of laptops in RP and I can tell you that I've seen almost 10 people with those BIG alienware laptops and I wonder why they'd put themselves in so much misery
Also, Macbooks are compatible. At lease 90% of them are. I've had no problems with them and no complaints from the customers. Battery life 'may' decrease, but blame it on Windows OS because the way iOS works is different from Windows, hence different power consumption.
I nearly wanted to put myself in that misery.
But end up my funds wasn't enough to fund that. So I gave up the idea.
I rather save to buy a new desktop. Alienware x51. 3k for the whole god damned set.
