It's been said over and over again that HTC really knows how to deliver on a fantastic solid device with an absolutely beautiful design and the HTC M8 is no exception. With all that great hardware it really needs some great software to go with it as well and Android KitKat really
enhances the M8 feel and overall use of the device. Match made in heaven!
As I was hunting around on the web and reading some articles I found this article from CNET that gives you a history of Android going all the back to the G1 (in the full article you can see all the Android versions back to 2008 I only included the version 4.x).
In truth, Google's first Android phone, the HTC-made G1, wasn't much to look at when it debuted in October 2008, with its trough for a keyboard and its bizarrely jutting chin. HTC was hardly a known brand, and we weren't even sure if we were getting a single Google Phone or an entire operating system. Still the humble G1, with its ugly design and few apps, kicked off an Android avalanche just the same.
Now in 2014, Android and iOS both command the smartphone market. Yet for all the platform's success, too many versions of the operating system are available at the same time across handsets and carriers. Whether you call that fragmentation or not, Google is actively trying to change it. When the company released version 4.4 KitKat in 2013, it made a big push to make its operating system smaller, so that it could run on budget devices with small amounts of internal storage and just 512MB of RAM (most flagship Android phones have 1GB or more). And yet, while some Android device manufacturers are starting to build KitKat phones, we still see plenty of brand-new low-end devices released with Jelly Bean 4.3 and 4.2. At least for the foreseeable future, the fragmentation problem is here to stay.
