Mackbook Pro by Apple: highly advanced technologies in an easy to use, easy to transport laptop. Based on my experience I can suggest it to everybody who's into photography, graphics, music and video editing: it will never let you down.
Apple MacBook Pro 15" Even though for many years my livelihood was supporting windows based platforms in IT, the best compute I have ever acquired was my MBP 15". the user experience, stability and productivity is so far beyond the windows platform. I had just received a brand new Dell E6410 at the Time beginning of 2011. but it was horrendous. I spent the $2k myself for peace of kind compute for personal and work and have never looked back.
