I was as annoyed as you were about this and just now found a perfect workaround to put the recycle bin to the taskbar. So I thought I would go through the trouble of registering to this forum to share it with you.
On this forum I found a way how to get old Quick Launch back:
*** REMOVED ***
" 4) Quick Launch Toolbar. Windows 7 made an attempt to remove the quick launch. There is still a way to bring it back in current builds. To re-enable it, do the following:
* Right-click the taskbar, choose Toolbars / New Toolbar
* In the folder selection dialog, enter the following string and hit OK:
%userprofile%\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch
* Turn off the “lock the taskbar” setting, and right-click on the divider. Make sure that “Show text” and “Show title”
are disabled and the view is set to “small icons”.
* Use the dividers to rearrange the toolbar ordering to choice, and then lock the taskbar again. "
After doing this you can easily place recycle bin or any other icon there. The bin works just fine so you can drag and drop anything there to delete it.
