I really like all the effort devs have been making in the homebrew entertainment area, especially emulators. It would also be nice, however, to see the functionality of the PSP expand into other areas. There don't seem to be many full-functioned text viewers/around (can view embedded image filesm has different font types and font systes, etc.) and it seems that pdf reader development has stopped entirely.
Given the possibilities of homebrew apps, I'd like to see my PSP as a console that has multimedia+extras. Does the DS have better apps in the non-entertainment areas?
