Root, JailBreak and Legality

You may encounter many such jargons used by many who are in favor of up-to-date technology about "Gadget" (A gadget is a small technological object such as a device or an appliance that has a particular function typical examples are smart phone, tablet). 

Root: 

    Rooting enables users to use the superuser, or root, permissions of the Linux-based operating system (OS)(Android is based on Linux system) thus have more control over it,thus overcome limitations carriers or manufacturers put on your devices. One example is Amazon Kindle Fire, the Android on the Fire is extensively customized to allow users more easily buy stuffs from them, and has many limitations. Another example is the fire-saled HP TouchPad (TP), the WebOS does not have as many apps as on Android, thus a totally new Android has to be installed on the TP.

    Advantages of rooting are: more freedom to control your gadgets, fun to explore

    Disadvantages are: risk of "bricking" (Firmware cannot start and run on your device) your gadgets and loss your data; void your phone’s factory and/or service provider warranty  

JailBreak:

My fresh taste of Kindle Fire

I would say it is a great little tablet with excellent value considering its sweet price ( I got it in an even lower price).

• It is not as great as a kindle keyboard or the new 4th generation family as a book ereader without e-ink technology.
• I notice there are many complains about its no physical volume buttons, no cameras, no expansion slots etc.   
• Without the physical buttons is indeed a drawback. What I really want is one button (as the "U" button on Nook Color) which allows you quickly return to the home screen. If it had hdmi port, that would be great.
