I found this list of Eazel Nautilus functionality items that they say Mac and Windows don’t have. Here’s my breakdown of it.
* Zooming in every view, from 25% up to 400%
Why? Wouldn’t setting a font size to 16 be enough?
* Icons can be arbitrary sizes and are individually resizable
Again, why? I could see a slight advantage to setting an important file’s icon to bigger than another. less-important file, but that still seems only slightly useful. Also, the Mac can do something similar: You can add ‘Label’ to your list view windows, and then sort by that. So if you label 5 files as ‘Essential,’ they’ll show up at the top, together. No clunky larger icons necessary.
* Icons based on document content, including embedded text for text files
What OS doesn’t do this? When was the last time you saved a Photoshop file and it got an icon that wasn’t Photoshop-related? Even PS JPEGs get a little JPEG marker on the icon. And the ‘text of a text-file inside the icon’ thing is ridiculous. If you don’t know what the file contains by what you named it, you’re an idiot.
* Emblems, which are little satellite images expressing file attributes, including user-assigned attributes
I can’t tell how this would work, so I dunno. Seems overly complicated for an icon, though.
* Sound previewing by hovering over the icon
I can hear the cacophony of mousing over multiple files in a window… no thanks.
* Extensible, componentized viewers (ie, you can read a text or other type of file right in Nautilus without launching a separate app)
Should the OS be what you use to write text? Is it really that hard to open SimpleText?
* Extensible, componentized directory views (a little hard to explain, offering type-specific views that put the functionality at the user’s fingertips – the best current example in Nautilus is the “view as music” feature)
Can’t you just do this in Audion or iTunes? Why does the OS have to do it?
* Annotations, where users can write and retrieve notes about any file or directory
‘Get Info,’ anyone?
* Attribute-based searching – ie, show me all the files I marked important
Sherlock can search by ‘File label is essential.’
* “Text services” where selected text is used to parameterize a web request
Huh?
* Drag and drop customization, including a cute way to specify gradient washes simply by dragging a color near an edge multiple user levels where the software reconfigures itself to support users with different appetites for complexity
Not sure about all of that, but OS X has that drag-n-droppable customization that Jobs showed at MWSF.
Overall, as far as I can tell, nothing groundbreaking.. Things they said no other OS can do are either not worth it or can be done by the Mac OS, and mostly Windows, too.
