The iPad is certainly a much better reading/watching device than an authoring one, at least in these early days. Still, its impressive portability makes me want to see how suitable it is for blogging. After all, the best blogging client is the one you have with you, and all that.
Also, I like to play with it.
Magic space tablet from the future, take me away!

I wrote my last post in the Blogger editor (copying in bits that were written in iTunes), which was workable, but hardly ideal. Mobile Safari does not support rich text editing in HTML with
contenteditable, so I had to settle for Edit HTML mode over Compose.
I'm happy to say that the toolbar works when you select text, so I didn't have to type in the bold or link tags myself. Scrolling, however, was pretty painful: though iPad often allows scrolling of
overflow: auto elements using a two-finger scroll, this does not appear to work on a
<textarea>. My only recourse was to drag-and-hold the insertion point at the top or the bottom and wait for the painfully slow scrolling to show me what I wanted.
The new editor's Edit HTML also lacks photo insertion, though with the lack of upload support in the browser I couldn't have done more than pick from Picasa Web Albums.
In all, the post editor is there, but you'd likely be happier e-mailing a post using Mail-to-Blogger unless you were really committed to a bit of formatting, linking, or adding an After the Jump marker.
