Well, thats not a stupid question.
The truth is, most apps work just fine...such as photoshop (my dad upgraded to 10.3 and it worked fine), but sometimes, for some people, things do get messed up, for example, permissions, plug-ins, etc.
There are other things too, like when an app installs kernel exentions for its functionality (like VPC), these extentions could have been compiled with an older version of GCC and therefore incompatible...I hear its (the ABI) finaly has been "finalized", and changes to the compiler wont break things anymore. But this was the case with 10.0 to 10.1 and 10.2....
Also, some applications work around bugs and do things differently, and then when those bugs are fixed in the next release, application behavior can be not what the developer expected...or when apple decides to "depreciate" certain api's an app can fail or behave wierdly.
But, TBO, most apps don't need to install stuff all over, but the ones that do, are usually the ones that suffer the most because when upgrading the system instead of doing things clean, the OS provider cant possibly know all of the changes to permissions, symbolic links ect. that some of those programs and applications change, so yes, it is always better to clean install when upgrading. Especially, comming from windows, I have this conditioning where thats the only way I'll do it.
