What's wrong with byte buffers? Serious question, as I use them all the time whenever I do OpenGL-ES 2.0 surfaceviews for android apps.

Well, you don't really have an alternative for that (short of writing your rendering code with the NDK, as I ended up doing).

The overhead of all the crap I had to do just to get coordinates from Java to OpenGL was downright ridiculous.

Nothing is wrong with byte buffers. Use them where appropriate. The advice is to stop when you find yourself implementing a full-blown memory manager / quasi-malloc in user code on top of byte buffers...
