I am much less important than I was years ago but I still have my moments.

I am instantly comfortable but I enjoy one side more than the other.

I am how you get to college and also how you won’t.

I am easily forgotten but sometimes the star.

I am able to make up for mistakes.

I am hard and also a little soft.

I am round but not.

I am obsolete.

What am I?
