There are times when I'm traveling ultra light and just have an iPad and my phone. This is usually what I do when attending conferences, or when I'm traveling and I don't expect to do much coding or writing. But stuff comes up even when I don't intend on doing work, and the ability to make small fixes from my iPad would be a big help.

I'm switching to a 13.3-inch Macbook Air as my main computer (with a 27-inch external display). We'll see if this changes my view on not bringing my laptop places. Still, the iPad is much lighter than an Air and gets incredible battery life.

I might even be out at a coffee shop on the weekend and realize that there is something I want to fix on a website. If I'm out at a coffee shop, relaxing, reading some stuff, I almost never have a laptop with me.

It isn't a question of cost, it is a question of comfort.

When you get an iPad you realize laptops have instantly become less useful. iPads fit into a tiny bag, they have crazy battery life, and they can do many things as well as a desktop. It is a no brainer to carry them with you instead of a laptop, as they do 90% of the things you need a computer for very well.

Having a nice text editor/FTP program would be greatly welcomed.
