Differences between NSTableView and NSCollectionView
I'm trying to decide which path to take for developing my Snow Leopard app. First, I should preface with the obvious differences:

`NSTableView` can have multiple columns of data for representing different parts of the same "element" of data (a row) where `NSCollectionView` can display a grid of data as well, but every row+column combo is its own element. For my purposes, assume I'm dealing with a single column.


   1. As far as I can tell, `NSCollectionView` items are `NSView`s which all must be of the same dimensions. Also, unlike `NSTableView`, collectionview items are copied to the `NSCollectionView` instead of being provided as needed by a `dataSource` (I'm uncertain about this, please correct me if I'm wrong).

   2. `NSTableView` uses `NSCell`s if you decide to customize the display of rows. As `NSCell` isn't an `NSResponder`, how does one handle events (if I wanted to add some sort of accessory to the cell, like how the Arrows in iTunes work (although, iTunes is Carbon). I've seen some `NSCell` subclasses in IB which appear to be equivalents of their `NSControl` brethren, but what if I want to have `MySweetView` objects in an `NSCell`?).

   3. Both seem to work about the same with respects to Bindings, correct?

   4. Finally, `NSCollectionView` appears to play nicely with animation of its elements (for re-arranging items, or filtering them for example). Can `NSTableView` do this with its rows?

Anything else I should consider?
