Your comments

I would love to see this feature as well.
Oh, I just thought this is what it is doing:
- you still can code everytime everywhere, you just need a connection to push and pull.
- an Internet connection of both, your iPad and your computer could help to push, whenever you are not at work/home.

Of course it's not the same as having native version controll support on the device directly, but at least you could work anywhere and be connected to your repo through your computer.
I think, that most developers have a running server, so for them it would be no difference.
The way I'm using Textastic now is copying all or some files to my ipad, modify them, copy them back to my computer and then push them from there. This process could be improved, doesn't it?
It's not the perfect solution, and yes, it's not for everyone, but it's better that living without it at all just because of some licensing destrictions.
Any you would not have to update the app just because of a change in any version controll system, because the real version controll management is done on your computer. It would also support tones of different vcs from the beginning.

"The idea [...] is to cut the dependency of the laptops/pcs." Well, I bet you'll never code something totally without a computer anyway, at last you would need one to run your code. So my idea might help transfering file changes...

But I don't want to say hey, this is The way to do it, and it's great, and of course I haven't thought about it throughoutly, just an idea, I wanted to share and I love your comments, especially the critic ones.
global settings are fine
but please let the user enter file extensions on their own. (not just having a few with an on/off switch).
it would be cool, if it could not only ignore some filetypes, but also files ending on @2x.png or -hd.png, cause sometimes you still want the images, but you don't need it in 100 different versions.
... but still no git :(
usually it takes about a week
you are waiting for review for about 5 days, 1 day in review and another processing for the AppStore. But this is just an average, it can be a lot faster or it can take longer, depending on how many other developers are releasing their apps/updates.
best would be:
project/filename - "TitleOfPage" - "Icon of page"
the iPad 2 mirrors the whole screen to the external display on its own.
iOS 5 will support something like textExpander for free right in iOS.
You can define your own words and use them in any app.
Why would you like to print your code?
