This is a hammer.

It’s a good tool, but it only does a few things really well. It’s really good at driving nails into things and it’s pretty good at getting them out. That’s about it.

This is a pencil.

It’s also a good tool, and it also only does a few things really well. It’s really good for writing, especially if I want to be able to erase that writing in the future. Sometimes we make mistakes and it’s nice to be able to deal with those mistakes. It’s like the hammer; it does one thing well, and it does a pretty good job of undoing that thing.

This is a Leatherman.

It’s a good tool. The Leatherman does lots of things. It can act as a pair of pliers, a screw driver, a kinfe, a saw, etc. It does lots of stuff really well. But it doesn’t do everything. In fact, it would do a pretty poor job of driving nails. If I have to drive a nail I’ll still go for the hammer. The Leatherman will never totally replace my hammer.

This is an iPad.

It’s also a good tool. The iPad also does lots of things really well. It can take pictures, record video, browse the web, play music and movies, etc. But it doesn’t do everything. Some things are easier, with pencils. Leaving a quick note for a colleague is still easier with a pencil and a post-it note than with an iPad. The iPad will never totally replace my pencil.

The iPad is an additional tool in my toolbox. It’s a great tool, but it wont replace my pencil, and it won’t replace my entire toolbox. Certainly, the iPad is a very versitile tool and it may replace some tools, but it won’t ever be the only one.

If you have to drive a nail into a piece of wood, nothing beats that hammer.
