After having been coding in Windows inside OS X, using Parallels, on my Mac Pro for a day and half I still feel very weird about the whole thing. (Getting my laptop's Windows installation transferred into a Parallels' virtual hard disk image was a long and tedious process and I won't bore you with the details)
Using Windows inside OS X just feel plain strange at the moment but I like it so far. Being able to run both OSes at the same time is so much more convenient, I don't have to switch screen/keyboard/mouse inputs, or keep two sets of emails and web bookmarks, and I can just drag-n-drop files between the two OSes. Despite running inside a vm, Visual Studio 2005 works very well. It runs and compiles almost as fast as on my Core 2 Duo 2.4 GHz Dell with RAID 0 drives in the office but I think the 2.66 GHz Xeon processor helps! 🙂
Anyway, the Mac Pro is everything that I have hoped for. Yes it is expensive but given my last mac lasts over 4 years I think it is a good investment. It does mean that I have to forgo the Xbox 360 for another 6 months or so but I don't have time to play game that much anyway. In fact, my Mac Pro is so good that I spent most of my time on the mac and didn't play even one second of Halo this weekend, normally the designated Halo time of the week.
