Eleventy-two

Edit
So back on my PC now, and some other points I would add to the above. As the above proves the iPhone WordPress application also lacks any sort of spell checking beyond auto-suggestion. It does however let you write a draft post and upload it without publishing it, so if thing of something on the road you can still write about it and correct it once you back.
Set up of the application was relatively easy, other than miss typing my domain and user name on the silly touch keyboard. You do however have to do is ensure that remote RPC is enabled if you installed WordPress yourself, so it’s worth turning this on if you think your going to use the application in the future.
As I said above one of the menus failed to draw properly when I was testing the application, but when I restarted it corrected itself and didn’t really cause any usability issues.
Overall I think for the avid blogger the WordPress application is worth adding to your app collection, it is free after all, just don’t expect to be writing essays on it.
