Ever get tired of the same ol' Kindle, with its rectangular shape and book-like features? Yeah, neither do I. Which is why it's great news that Amazon is releasing four new kinds of Kindles at different price ranges.

The lowest-priced, which is just your basic "Kindle", is the same as its predecessors. It's smaller, lighter and "turns pages 10 percent faster"...I'm not sure what kind of page-turning madman sat down and compared that, though. Nonetheless, you still get your favorite e-reader from before, only for $79.

Next up is the "Kindle Touch", a mere $20 more than its less-advanced version (bringing our total to $99). This aptly-named e-reader brings a touch-screen for your page-turning, note-taking, searching-and-shopping pleasure. Again, enhancements have been made to prolong battery life, reduce the weight and make it smaller. There's also the new "X-Ray" feature, which Amazon says lets users "see all the passages across a book that mention ideas, fictional characters, historical figures, places or topics that interest them, as well as more details descriptions from Wikipedia and Shelfari". Avid wikipedia-clickers, beware, as this may just eat hours of your day in a single book.

The top of the line e-reader is the "Kindle Touch 3G", available for $149. This version carries all the specs of the Kindle Touch but with, you guessed it, 3G. The best part? It's free! Now you can have access to the Kindle store wherever, whenever, without the need for Wi-Fi hotspots.

Perhaps the most exciting news to come out from Amazon's tablet event is the release of the new "Kindle Fire", a $199 tablet, which shouldn't be confused with the aforementioned e-readers. With this tablet, you can browse the entirety of Amazon's selection, ranging from movies, music, shows, games, books and magazines. Of course, these virtual products still require buying. And don't let the measly 8GB of storage space scare you off: Amazon has provided free cloud storage for all of your digital content, available for re-downloading whenever you desire).

The Kindle Fire also comes with Amazon's new "Amazon Silk" - a type of browser that delivers faster speeds. This is done by Amazon taking part of the page-loading away from your device, and instead onto their servers. With loading times split between Amazon servers and your Kindle Fire, pages should come up faster, allowing for a swift peruse of the internet.

The Kindle can be bought today, while the Kindle Touch and Touch 3G are available for pre-order now, with shipping on November 21st. The Kindle Fire can be pre-ordered today as well and will ship out on November 15th.
