You could get a stylus if you're able to hold one, some are designed for a capacitive screen.
And the iPad has a dock for a physical keyboard.
Regarding the iPad, Am I the only person on the planet who cannot use a capacitive screen? I'm physically disabled and must type everything with one knuckle. I don't have the dexterity to do finger-tip operations. A friend lent his original iPhone to me for several minutes, but I couldn't even get it to acknowledge my existance! I can use resistive screens, just not capacitive ones (don't get me started about Multi-touch either).
