I also do a lot of Python development and a bit of HTML/CSS work. I recently had to toss up the pros and cons of an MBP versus a Dell XPSM1530. The 1530 won on the grounds that it was £700 cheaper than the Mac, more powerful and a better screen. The related cons (Vista, being a Dell) aren't so bad and I'll upgrade to Win7 when it comes out.
