I'll try to keep this as short and to the point as possible. I need a new laptop, I don't necessarily need a mac but I do prefer the OS and MacBook form factor, I already own an ipad and an iphone so it would be helpful to stick with apple. I'm about to start a postgraduate (part 2) course in architecture, I want something that's powerful and will easily stand up to pressure I put it under. Programmes include photoshop, autocad, sketchup, revit (parallels with a mac), 3DS max, vray and possibly more. I really want the new MacBook pro if they ever announce it, but its getting close to the start of term and I may have to bite the bullet and buy an existing MacBook pro or windows laptop. Now the two 15" retina MacBook pro's are £1600 and £2000 I think off the top of my head (apple website down) both i7, 128GB and 256GB memory or maybe 512GB in one? with 16GB of RAM again I cant remember of the top of my head. Whilst waiting for the release of the new MacBook and looking at the current generation I have browsed for windows alternatives and I've come across this https://www.amazon.co.uk/Dell-Inspi...TF8&qid=1473235246&sr=8-1&keywords=dell+15+i7 A 15.6" Dell Inspiron quad core i7 16GB RAM, 1 TB Plus 128 GB SSD - you can see the rest of the specs for yourself. For a little less than £1000 Can somebody tell me, how this matches up to the top of the range retina MacBook pros and if its worth spending the extra £600 for a mac over this Dell laptop? I'm not clued up on specs or generations of processors etc, I love apple laptops and I've used them forever but the specs in this windows laptop seem fine and its much cheaper. If they announced the new MacBook today and released it in the next month I would probably wait but time is against me with a new term starting in a few weeks. Thanks.
