At Present the confirmation message is sent as simple text which is not very user friendly.

You can edit and modify the message template as needed. A lot of the text comes from the DB and is collected on a per event basis. I'm not sure why you state "simple text is not very user friendly". I do agree that html text is more attractive to read (assuming the mail client downloads your images etc)

Is there a reason for not sending it as html with the ability to show  the same formatting as in the browser?
How to change it to send html text?

There are a few things you'll need to do to send a MIME mail.

1. add fields to the db to hold the html versions of the receipt text / pay later receipt text / (and other fields if any)

2. add an html template message: CRM/Event/Form/Registration/ReceiptMessage.tpl, CRM/Event/Form/Registration/ReceiptSubject.tpl

3. Change the email sending code to compose a MIME message using both the text and html versions from the db
