This will depend on the libraries you use. For example if you some how get boost libraries to compile for the pocket pc and use them to create your software on both pocket pc and on desktop then the executables will be close tot he same size. Like the other poster that answered this question said the libraries made specially for the pocket pc and hand held computers are stripped down so that you can make the software smaller. The problems I ran into when porting my Yahtzee program back and forth from XP to Win CE was the space on the display. now you might think that doesn't matter for programming for blind folks but as soon as you start making sure your software works for Braille output devices you will find we also have to make sure our screen layouts are as good as those sited programmers make. One important thing to do when creating software for a pocket pc and the desk top is always start with the small device. All the things on the small device are normally available on the desktop p but a good 40% of the stuff on the desktop is not as easy to do on the Pocket pc. This is changing with windows mobile 5 and 6 but if you want your software to run on a lot of devices you may not be able to use .net because some devices will not run some versions of .net. There is a lot to this and really the only way to learn is to dive in and write some programs for the pocket device and see how it goes. I have done this lots though and I will warn you if you start with the desktop and try to back port it you are going to run into lots of trouble.

Is it easier to write an app for a pocket PC device or for a desktop OS such as Windows? In other words, if I were writing a calculator for a pocket PC or desktop OS, both containing the same calculator features, would they both necessitate the same size executables? I'm wondering if one platform might add much more functionality with less coding overhead. The ultimate goal is to have many of the Microsoft windows calculator features on a pocket PC without a huge file overloading my device's ram or OS. Any suggestions?
