Been tinkering - the folder that is opened using the /Volumes/ trick does not show the proper icons for the drives. It also doesn’t give you the network. I picky - I want to see my iPod looking like an iPod. So I figured out that I should be able to open the Devices window.
In Finder, press Command+Shift+C to see the window I want. I can not make an ailas to this window, so I decide that some AppleScript attached to a folder as a folder Action could do this for me.
So, here’s what I have done.
1 - Copy and paste this AppleScript into your Script Editor:
2 - Save it in ~/Library/Scripts/Folder Actions Scripts/ (you may have to create this folder)
3 - On your Desktop, create a new folder and give it a sensible name
4 - Right click on the folder and select More... > Enable Folder Actions
5 - Right-Click again, and select More... > Configure Folder Actions
6 - In the left hand column of the window that opens, add the folder
7 - In the right hand column, add the script using the + (it should give you a list of scripts - the new one should be there)
8 - OK the window
9 - Double click on the folder - the Devices folder should open!
Almost done, just two more things to do
10 - Apply an icon (if you want) to the folder
11 - Select the folder, and do a Get Info. Set the permissions for you from Read & Write to Read Only. This stops you dragging things into this folder as really it’s a dead end and serves as a trigger.
I did try saving this as an AppleScript application, but it didn’t work, hence this method. You also can’t drag files onto it and benefit from Spring Loaded goodness.
IUf anyone can get the folder I want as an alias, please let me know

Until then, I hope this is of use to others.
