Having to cater to the absolute lowest common denominator holds back progress. Why should I be forced to adapt your preferred workflow and limitations if I prefer to have a wide-screen monitor or another standard tool.

Market decided wide screen is better on pc, you blindly followed. Market decided that isn't the case on any mobile platform which in case you missed it vastly out numbers pc.

There was never an argument about whether wide screen is better or not, only that larger column counts make it harder to read your code.

Using obscure single letter variable names also make your code harder to read, is using decent variable names catering to thw lowest common denominator as well, is that a bad thing? Are we holding back progress because we use descriptive names for things?

Make your case about column width, there are valid arguments for longer widths. "Because wide screen is better" isn't one I will accept, last I check no other written media prefers being printed in landscape.

Without implying whether one position or the other is stronger, I want to point out that even when you're on a wide screen it's not uncommon to take advantage of that and have at least two screens side by side.

You are assuming too much about me without having a single clue.

Your choice. Mine - not to work on cell phone. This might change if they will stop crippling smartphones and let it to be hooked to a decent monitors / (future high quality display glasses)
