Hi, I'll start of by saying I understand the basics of laptop technology and what makes a good unit/better unit, but I'm certainly not the most clued-up when it comes to heavy jargon. My current laptop (an HP) is coming to the end of its life and I'm looking for a replacement. I work in a high-performance job that requires a very capable machine, and have it in use for at least 15+ hours a day. Along with that, I do some fairly heavy-duty music recording and editing. I have been looking at getting a Macbook Pro with Retina Display (15"), but really want to know what people thing of any alternatives, if any exist. The Dell XPS 15 seems fairly good, but reviews of it complain about heat, noise and the trackpad - things which I know the MBP excel at. The price is one issue - although I would pay it. There don't seem to be any alternatives for the specs I'm looking for (quad-core i7, SSD, minimum 8GB RAM), although some online manufacturers do build laptops for relatively low prices. I'd be slightly nervous about purchasing one without a known manufacturer/make behind it. Does anyone have experience of these? I accept posting on here will likely get me mainly pro-apple comments, but I would appreciate your thoughts. Thanks!
