Check out this Apple video about working with multiple emails both iPad. It's a new feature for me, and I'm also betting for a lot of other people. The short versi is that you can use the handle at the top of an email that you write to drag it to the bottom of your screen, where it stays anchored. This allows you to browse your inbox. If you ly have e email anchored, tap it to put it back in place. If you have more than e, it gives you a Safari tab type view to choose the e you want. It's a nice feature. Oh, and it works in portrait and landscape mode.
