It used to tell you

the time

Now it tells

you what to do

It used to remind you

of someone close to

your heart

Now it reminds you

to take care of your

heart

It used to just

provide power

Now it talks to your machines

and tells how you much they

are consuming

They used to help you

see clearly

Now they help you

to see more
