I'm trying out the Blogger app on my iPhone right now. I like being able to manage the posts a little better, but the app isn't switching to landscape orientation when I turn my phone around. I have large and unwieldy thumbs. Consequently, I prefer the larger keyboard.
I'm also disappointed that there isn't an app for the iPad. That seems a little silly. Of rather blog on my iPad than on my iPhone any day. I might not use the app again.
On the upside, adding pictures looks like it is easier on the phone than on the desktop. I could even take a picture of my cool new Superman ear buds and post it straight away!
For a less-than-part-time blogger like myself, this little app should suit me just fine.
