Do I have to get all new apps if I convert from PowerPC Mac to Intel?

but they perhaps loosely paraphrase " How compatible your application is with Rosetta depends on the type of application it is. An application such as a word processor that has a lot of user interaction and low computational needs is quite compatible. An application that requires a moderate amount of user interaction and has some high computational needs or that uses OpenGL is most likely also quite compatible. One that has intense computing needs isn’t compatible. This includes applications that need to repeatedly compute fast Fourier transforms (FFTs), that compute complex models for 3-D modeling, or that compute ray tracing."  as including Photoshop among apps that have " intense computing needs " - maybe the wiki author found that to be the case on an older machine?.
Very loosely!  Actually that quote from Wikipedia is wrong with regard to Adobe Photoshop and should be corrected (at least as it applies to version 9, CS2, after which, later versions, starting with CS3 do not need Rosetta in any event).
While I am not sure about the rest of that quoted phrase (acually in most of my posts on this forum indicating my solution for running PowerPC applications [Installing Snow Leopard with Rosetta into Parallels] in Lion or Mt. Lion, I do note: "Computer games with complex, 3D or fast motion graphics make not work well or at all in virtualization." I do, however, see this as a virtualization problem and not a Rosetta problem (as opposed to these programs running on a computer that can actually boot into Snow Leopard and run these programs in emulation, where Rosetta should not pose a problem).
My experience with Adobe Photoshop is limited to CS2, which is now available for free download from the Adobe website.  My uses for this program are limited, such as when one frustrated Mt. Lion upgrader noted that Apple should post a flag about the loss of Rosetta (see my graphic posted above).
But my understanding is that Adobe Photoshop (at least up to version CS2) does not require any rendering, which could be hampered and slow in virtualization and perhaps additionally with Rosetta. 
Use of Photoshop 9 (CS2) appears to be similar to use of Freehand MX and none of the users of either of these powerpc applications have come back with any complaints after my suggestion to them on how to continue to run these powerpc apps in Lion or Mt. Lion.
