One of worst thing I have ever experienced was this comment on my profile on versiontracker:
This was the lamest thing I've ever tried. It starts by popping up disjointed out of place overlapping windows then an alert box pops up telling me that I don't have a 64MB video card just to make it appear to be an advanced piece of software, sorry I only have a Radeon 7000 32MB and that my computer isn't good enough for this piece of shit software. The UI is crap, it's way too buggy to take seriously and it's down right ugly. I felt like I had a red headed step-child with head lice on my computer. It does work great with AppZapper.
You are no PhotoShop, keep dreaming. I really hate when people spew things that just aren't true.
A great source of inspiration is: http://osx.iusethis.com/
Go though some programs while thinking "I can do better than this". Pick a useful tool that you actually can code with little effort.
Then get the payment system working and try sell it. It's ok if it doesn't sell.
Then start coding a bigger tool and use the payment system and homepage setup and all the knowledge you have learned from the first project.
