Tangential Ramblings

Why (oh why oh why) is the USB socket (and associated plug) not 180° rotationally symmetrical?  Given that they're generally at the back of your machine, it would save a lot of faffing around and unnecessary jiggery-pokery.  (Here's further evidence of the need for the degree sign to make it on to the standard keyboard, btw.  My current process for getting it into a 'blog entry is Open MS Word | Insert Symbol | Select degree sign | Copy this from MS Word | Open Notepad | Paste into Notepad (to get rid of the font size formatting) | Copy from Notepad | Paste into the 'blog CMS's RTE | Close MS Word | Closed Notepad | Take a well-earned nap.)
