I am making this post from my iPad. I am going to compare using the iPad app "Blogger," vs the computer version of Blogger.
I, personally like the computer version better. The computer version allows you to see all of the cool gadgets that I have put on my blog. The iPad just allows you to posts. The iPad app does, however, allow you to make a blog post from anywhere, which can be handy if you need to make a sudden post about something you saw and HAVE to post about it.
