The interview with Leman really demonstrated the possibilities of iMovie and the iPad. It’s totally portable, it’s pretty non-intrusive as compared to a big videocamera, it can be edited on the go, and uploaded that way, too.
I’ve been working mostly on City High Review, so I haven’t had a HUGE amount of use for the iPad, but the WordPress app is really nice for monitoring and editing your website. I’ve also been using the Evernote app a lot to write notes and take pictures I want to keep on the go.
