Why are you judging someone else's productivity methods?

Good developers write apps to scratch their own itches, and this seems to be a laudable example, whether it scratches your itch or not.

Your comment demonstrates the subjectiveness of the "right tool". I personally have no problem coding on a laptop, and even find myself more productive with the MBP's trackpad than a mouse. While I don't like working on the iPad, I can imagine somebody having as different an opinion on that as between your opinion on laptops and mine.

> Even developing on a laptop is utterly painful - single small screen, no mouse, no real keyboard. It is probably nice to look at the sea while developing but it is not productive.

I think what you meant to say was "but I'm not productive this way." Clearly many developers are more than productive without a big screen/multiple screens, mice, and external keyboards. And as someone who has been shipping for several years with nothing but a 13" screen, I'm definitely one of them.

In fact I'd argue the ability for me to be totally mobile and work from wherever I want, whenever I want, makes me _more_ productive than being tethered to a monolithic workstation. There's a lot more "oh hey, that code I wrote last night kinda sucks, let me fix it before I hop in the shower" and a lot less "oh I should probably get around to fixing that thing when I get to my workstation."
