Google is forcing its browser, Apple has its own, and Microsoft has one as well. I don't see "regular users" using Firefox unless it is recommended to them by the "2%". So don't annoy the 2%.
I don't think you should. Every UNIX operating system has ifconfig. Writing a nonstandard tool instead of fixing the standard one is very antisocial behaviour from the Linux community, mirroring that of Microsoft. Have a look for example at how excellent the ifconfig program for OpenBSD is. These days Linux has become so popular, that it starts to pretend other operating systems and standards are no longer relevant.
Fire HD 6 - Quad Core but they seem kinda silent about the memory. And for a good reason, it has 1GB of RAM. That is way too little for Android. Wouldn't buy, no matter the price. Note how they also call "storage" as "memory".
