I have an iPad 2 :)
In fact I am busy typing this entry out on it. So far so good. I think I'll be blogging a bit more now that I'm also connected via 3G. Luckily the signal seems to be quite decent and speedy. The Wordpress app isn't the greatest at the moment though, I would definitely enjoy a WYSIWYG editor and a confirmation before uploading my entry. But it ain't that bad for a free app :)
Another much needed feature is the ability the pinch zoom the editor view, especially when correcting text.
Update: 2012-02-01: Switching back to Blogger from Wordpress :)
