However, if you can convince yourself to get a bit spendy look into tablets like the iPad or even the little iPod Touch. They either come with a calculator app or you can download one from the app stores.
The goal isn't to get an expensive calculator though, the real goal is to have access to a spread sheet app and an app for taking notes. I carry around a cell phone just so I can have instant access to the various notes I have for the different machines I work on. Think of it as an adjunct to the gray matter memory. In some cases when they are available I download and keep in the device manuals in PDF format. Such stuff in your pocket can be a huge time saver over trying to grab paper documentation or finding a laptop.
By the way there are options beyond Apple though I can't recommend them from experience. The other thing is that you don't have to buy new! In fact it is expected that next week Apple will release new hardware meaning that the old stuff will flood the markets as used equipment.
