I’ve been testing the iPhone app on my iPod. So far it seems like a really great way to post simple text posts. Forget about photos, lists, links, etc. The iphone interface does not make an ideal editor. Maybe with copy and paste but, personally, the virtual keyboard makes writing so much slower.
The one bug I found, and it might be iPod only, is that landscape mode doors not work. The ui elements do not display correctly, the buttons at the top of the screen.
The iPods auto correct spell check presents an issue also.
