lol any question is right, to answer yours... I am using Lion. the menubar mob you can get here [link] the media player is called Ecoute, you can get it in the app store. and as for the 'square folders' i am not sure what you are referring to? the docks on the side are Dragthing..
ah, Lion, I just downgrade my early 2011 MBP back to SL cause Lion get me much troubles (it's much-much slower than SL, and draining my battery so fast even I did a lot of tweaks that i can found in apple forum...maybe i should upgrade my RAM to 8GB first), gonna miss the gestures, launchpad and mission control T_T
and for the 'square folders', well, i don't know how to call it, but it's on the center of your screen.. everything is square and look so well organizing (even you named it unsystematic ). really love that..
ah, now that 'folders' is making sense great collections you have there (actually, i'm bookmarking rite now )
and for lion? well, i guess i just let SL breath more longer on my baby till i've spare time to get mess with Lion again, cause truly, Lion is really effective for my multitasking day if it had no problem and really good looking too (and hell no, apple didn't pay me for 'promoting' Lion )
