Disregarding that the original comment was probably sarcastic.
I agree with what you say but I think developing this kind of software is a great idea, nobody knows exactly where the future in technology is taking us but it is not so crazy to think that the mobile phone will replace the PC, the way I see it, in a not so distant future, you might be connecting a mobile device to a screen, keyboard and mouse and you'll use it as a PC, so making IDEs for mobile might be the future.
This is of course just me guessing, and there is one more side to consider: it might be more likely that mobile devices become powerful enough to actually use the same software we use on our desktop.
I can already connect my Droid 3 to HDMI monitor input and a bluetooth keyboard (actually Droid 3 keyboard is not too bad for development , I used VI many times via ConnectBot app). In the future, it will become only better: you will just put your phone next to the monitor and the keyboard, with no cables, and it will be like today's PC.

I disclaim again that this is my opinion.
