I am using gmail.com since a long time, it is really good to use and it is very helpful for me.
An andeoid user must have a gmail id to operate the android phone to start the play store and for otger things so I make id in gmail around 4-5 years ago and using it till now.
It is also very helpful whenever I registered on a new app, in the sign up adress it always ask for an email so I put it there and the confirmation email come and I verify my my accounts so easily.
It is also very simple to use and it is even very easy to make a gmail id.
