First off, its great to see another contender in the ring against Adobe.
Microsoft tried and failed with there Expression Studio software, but then again its not the first mistake they have ever made.
You guys have some solid programs and your Affinity Project looks great, but why just Mac?
Hear(read) me out, I have a big love for the Linux Community. Ubuntu is the distro I use a lot on my laptop, its clean, its simple and has came a long way from the days of old. With the new Software Center and Unity Bar you can't really go wrong. The only thing Ubuntu lacks is big business software.
There seems to be this thing about software you pay money for over something that is free, the free stuff just doesn't give people the same feeling as bought. So here is what I suggest, why not develop for Linux (Ubuntu)?
I know plenty of people in design that if they knew a solid design application was out for Ubuntu they'd switch. It's gawna happen soon Serif, Steam(games) are encouraging people to develop their games for Linux for SteamOS. these game will be available on the Steam client for Ubuntu.
Think about it, the more Steam pushes Linux, the more younger people will choose the free Linux OS distros that support steam clients. This means in the future there will be a pretty good opening for a solid design studio on Linux. Being the Adobe of the Linux world wouldn't be a bad thing, since the power house Adobe refuse to support Linux.
