I don\'t know if you can use cygwin, but do yourself a favour, set up your PC
to dual boot Linux & Windows.
That\'s what I did initially when I got into Zaurus development. I first allocated 1Gig of my hard drive too Linux, as time went on I found myself using Linux more and more. Now I have the 1 Gig devoted to Windows, and the other 5 Gig are Linux. I only use Windows for Pocket PC development and for my email with Eudora. Not that there are not a lot of good Linux email programs, I have just simply been to lazy to experiment with one that will handle importing my years worth of email archives.
I recommend that you give Mandrake or Suse a try, I tried both, I prefer Suse. Both installed flawlessly on my IBM A31 Thinkpad. My only complaint with Linux, is that I haven\'t found a text editor that I really like. Many people swear by Vim or Emacs, and they are pretty adamant about their choices, but I find them both pretty clumsy to use.
I know that I didn\'t really answer your question, but give Linux a try, it will solve your development box problem.
