And if your company has dreams of becoming a larger successful company, you are going to have to pull it out anyway. Its cheaper in the long run just to buy a Mac Mini or an older MacBook. I'd even argue its cheaper time-wise just to get the hardware instead of dealing with an unstable build server if you go the hackintosh route.
Why doesn't Apple make it possible to use its development environment (required for developing products to run on its hardware) in a VM? This seems like a user-unfriendly decision.
I'm curious which set of hackintosh instructions you used. I tried a long time ago to install Snow Leopard on a VirtualBox VM using iBoot, but I couldn't get iBoot to work correctly on the VM. I'd love to have an OSX VM for browser testing and CI.
Using VMWare Player is a much easier install. I run it on VMWare Workstation 8 (it may even work on 9, I don't plan on spending the money to upgrade right now) There is one little Unlocker tool to run that tells VMWare to go ahead and boot OSX. Lion runs extremely well for me. Yes this violates their EULA.
