I was one of the first few people to order a rMBP. I maxed it out minus the 768gb drive. Now I'm wondering did I do the right thing. My work goes as follows. I have 5 virtual machines all running windows 7 that I used consistently running Visual Studio, etc. I use the mac side to run PS 6 and iPhone/iPAD development. I currently hook my rMBP into a thunderbolt display. I'm wondering would it be a better solution to build a custom power-pc and run all the windows on that box, and use the air to remote into the pc when mobile, and use the air for iPAD / iPhone development and Photoshop. The reason for the PC idea is because I really want to run dual monitors and there are many times where I wish I had an always-on pc to do large downloads, etc. These are rare, but would be nice. The price would eventually be the same between the two solutions. Another hidden option is just to buy another thunderbolt display and run dual displays on the rMBP (I did this at work and it works really nice actually). Thoughts?
