Ask HN: Is Dell XPS Developer Edition a Good Replacement of Macbook Pro?

Hi, I've been waiting few months for yesterday's MacBook upgrade and I'm dissatisfied, as most of you. I read many comments about alternatives and one of recurring favorite is Dell XPS Developer Edition. Could I ask you about your experience with this model? I'm interested in high-end version (16gb and UltraSharp screen). Is it worth this money (less than Macbook, but still)? I actually want to buy "best machine money can buy", which is powerful (for JVM development, besides personal stuff like movies and web), but still easy to carry-on while traveling. Most of the machines are Windows-oriented, which doesn't fit my workflow and there's a limited choice of laptop fully compatible with Linux. Dell XPS 13 seems like one. Do you have positive experiences with this? Would you recommend it?

I just get rid of normal desktop and use mainly my office machine - heavy, powerful ThinkPad W541 with 32GB ram and i7, but it's plastic and the screen is so-so.

Thanks!
