I'd be willing to pay a reasonable fee for a Linux product. I'd suggest a Debian base, as I use Linux Mint. To the end user, my primary customer base, it has a great look and feel for those that are comfortable with Windows. While the OS is 'free' compared to Windows & other products, it shouldn't be implied that people that use Linux don't pay for their programs. I develop applications and expect to be paid for my work as well. And since I don't have to have large fees incurred to me for startup apps, as many are open source that can be built upon, in turn my solutions to my customers are often less expensive than comparable Win apps. My customers also aren't subject to various Viri that affect Win & Macs. For what it's worth.... Please figure this into developing a Linux version of your software.
