Also, you have some serious problems if you cant wait 30 seconds for anything. Seriously, people suffering from ADHD tend to have more patience than that. However as someone who sells high priced items that provide minimal gain, I like suckers like you.
Ok, you had good points until here.
Any (good) programmer, artist, writer, or anyone else who creates on a computer for a living will tell you that they hate unresponsive applications. Open a new file and wait 5 seconds before you can see it? It's distracting, and it breaks your train of thought.
It's not ADHD, it's the fact that we're used to, from the "real world", to have instant response to actions -- pull out a piece of paper and you can read it immediately. Put a brush to the paper, and the colour shows up instantly. The brain expects the computers, which are trying to model this real world interaction, to work the same way.
