To be honest, if you're using the browser there's not much in the way difference between using hotmail on any platform.

Once you click on the message to read it just touch where it says reply and use the drop down to select Forward.

The Hotmail website isn't too friendly so you could always scroll to the bottom of the page and select 'Mobile Site' - that's a much cleaner and stratforward interface.

However, you may wish to forget the web interface and use the built-in email client.

Go to "Settings" - "Mail, Contacts, Calendars" - "Add Account..." - scroll down and hit "windows Live Hotmail" and follow the screens through entering your email/password etc. Now you'll be able to use the iPads email client. You'll find it quicker and easier than the web interface (in my opinion)
