I haven't downloaded and used it yet, but there is apparently a new iPad/iPhone app for Wordpress: http://iphone.wordpress.org/2010/06/...s-for-ios-2-5/
I hope it works, because the old one didn't allow copy/paste and was buggy in other ways. If this works, the iPad could truly be my only computer for short trips, allowing me to leave the bulkier laptop behind.
Have you tried the app yet?
