I have been playing around after installing a beta from bigboss's beta repo that gets rid of recent apps, and only keeps backgrounder apps in the multitasking in bar. All the official apps work in he background (maps, app store, camera,etc.)
After freeing memory with sbsettings, (once again beta that "free mem" is not glitched), these apps takes a lot less memory than they did before. Mobile music only uses approx 10-15mb now, a lot less than before. I could run maps, app store, music, and angry birds flawlessly. this was all on a regular 3g.
BTW: Bigboss beta repo: thebigboss.org/betarepo/
the music controls also work fine in the "double click multitask" menu, as does the rotation lock. the ipones' as zippy as ever
