Amazon has just made their new Kindle for PC available for pre-order online, a move that turns almost any PC in the entire world into a fully-fledged ereader. The software comes on the heels of all of the big Win7 announcements today evens up the playing fields when it comes to PC-based ereaders.

Amazon has long had the Kindle but Barnes & Noble launched a PC ereader long before Amazon, putting them at a disadvantage. B&N also has versions of their reader for OS X, BlackBerry smartphones, and the iPhone/Touch.
