The media browser is working pretty great for me, but I think my needs are simpler than the typical Sonar user.  It's incredibly rare for me to add loops and bits and dabs of audio clips to a project, I'm mostly working in the old school way of just playing my MIDI instruments and writing music.  

But recently I had need of adding a lot of sound effects throughout a soundtrack-like project.  Inside the master folder for the project, I had a SFX folder where the accumulation of potential SFX were parked.  As I worked in Sonar, whenever I needed to audition (gun shot 1, 2 or 3?) and then add a choice to the SFX track, the media browser could easily open to my SFX folder because it was one of my saved locations.  And of course if it was the most recent folder I'd visited, it would already be open.

The only thing is - Even though I saved that SFX folder location so it showed up in the media browser's menu, now that I've moved on to other projects, when I open the media browser's menu - that added item isn't listed anymore.  I opened up one of these projects with SFX, and that item doesn't show up there either.  Sonar dumped my custom folder location - ?

The other thing I'm not understanding on this thread, and I think I must be misunderstanding something, is that people seem to be saying sub-folders can't be opened.  The browser works just like opening things in Windows, accessing anything you want - Like in the case of my SFX folder, that was a sub-folder of the project, and inside that SFX folder, I had several sub-folders of SFX types, and I could access all of them.  - Like I said, I must have misunderstood what I was seeing on this thread - I thought people were saying that you couldn't open a sub-folder.

Browsing through my entire computer works perfectly for me, just the same as browsing for things outside of Sonar.

Most people's needs for the media browser are probably more complex than mine, but for the use I've had for it, it's worked perfectly - (except for that odd thing of the saved location not staying in Sonar.)

1st world problem.  I, too, have too many samples, loops, etc.  If you figure out a system, searching (and esp. searching w/ computer help) is easy.  But most of my "samples" have been accumulated over many years and kinda haphazardly added.  I could spend the next few months figuring out a system and slotting all my samples as such, but that would be a lot of work better put to, you know, actually making some music. 
 
Instead, I struggle on w/ an unsystematic system.  The big libraries - SONY, Cakewalk, come under their heading.  The stuff I've picked up goes into smaller, separate libraries which I try to keep their name so I'll know where I got them from.  Unfortunately, - and many of them have nothing to recommend them for, but one never knows.
 
However, I seldom need to search through 10,000 kick hits - or even a 1000.  I have a good idea about which of my sub-libraries/folders has good kicks, snares, etc.  since I've used them before.  Sometimes too many choices are as bad as not enough, at least in terms of getting something accomplished.
 
I've also learned not to click on a name in the browser - both SONAR and Windows, as much as one naturally does that (esp. w/ the touch template getting more and more traction).  And I still do it, tho not nearly as much and never twice in a session.
 
As far as searchable browsers - sometimes I find them more frustrating than trees.  Take Alchemy, which has all kinds of headings to look in libraries.  Guess what, I find that less than useless.  I learned to look by library as I added them.  I know that biolabs will have a kind of sound(s), etc.  All the rest of the sorting just is a waste, tho I admit I'm not typical in that sense.  And I don't go to alchemy to find a snare hit.
