I started using a Mac for web development about 2 years ago. I immediately fell in love with MacRabbit's CSSEdit (Which has now become a part of their Espresso editor) because of it's live update/preview option. It allows you to make your CSS changes and see a webpage updated in real-time without having to save your CSS file.
I recently started a new job where I must use either Windows or Linux for development so I chose to run Windows 7 with Ubuntu running as a VirtualBox virtual machine. I am now in desperate need of a tool similar to CSSEdit that will run on either Windows or Linux (Preferably Linux).
What are you guys using for editing CSS on Linux/Windows and do you know of any way to achieve the real-time live-update feature?
