Exciting Launcher Dock - Ooh, Shiny!
"The Unity UI lets you drag and drop icons into the launcher/dock, à la Apple's Mac OS X"
Windows 2000 Pro and Windows XP (and Vista I think) let you have a separate pop-out 'dock' (called a taskbar) on each side of the screen and you can overlay more adjustable taskbars on top of them. An item in a taskbar can be any shortcut you have created and so you can have a folder full of other shortcuts as a 'docked' item, which when clicked effectively opens up a custom 'dashboard'.
I've been 'driving' my Windows computers for 12 years using pop-out taskbars and was well pissed off when these were removed in Windows 7.
At the moment, there's nothing I can do with Windows XP that I couldn't do with Windows 2000 Pro (which admittedly needed some extras installed to get full networking magic going), so I'm wondering what OS development is actually doing, at least for the end-user and ordinary domestic consumer.
I'm not a windows fanboi, I'm a fan of things that work and keep working, like my seven year old Acer laptop running XP.
