Go ahead and spec out a similar machine from Dell, HP, or Lenovo.
Last time I did that I was able to put together a machine comparable to a Mac Mini for about 50% of the price, and a Macbook for about 70% of the price. On average, the "Mac Tax" seems to be about 40% of the list price of a Mac.
I still bought the Mac mini and the Macbook Pro (thought that was tough, I could have gotten everything I actually wanted (hardware-wise) from a Macbook Pro for about the same price as the Macbook). When the choice is Windows vs UNIX-with-actual-applications, the Mac Tax is worth it. But it's still real.
