Impossible to replicate the experience of a desktop, anyone that is accustomed to that... probably no.

I have wanted to use jira etc to look up information and that just ends up being a problem of how one's company decides to limit access.

I have a vm I connect into via ShellFish (same dev as Working Copy) for when I want to checkout/fix/deploy, but it's a rarity that I need to do that.

This suggests that the market for mobile phone development tools is probably efficient and the supply of existing tools satisfy the existing demand at an equilibrium price.

So as a business, it is probably not a great market to enter. Even worse, mobile applications require third party approval and require unpaid maintenance when mobile platforms change technical details and business details for their app stores.

And of course, the app stores are terrible for discoverability and have high overhead.

Good luck.
