I installed iOS4 yesterday; here are the first impressions of the bluetooth keyboard support. Being able to use a keyboard with the phone, without jailbreaking, is absolutely great. The phone starts to become a really viable writing platform; for blog posts, mail, and fiction. I’ve got one of the old foldable keyboards originally designed for a Palm, and it folds down to the size of a paperback book. This makes it really easy to write while on the move. Some of the Best Gaming Keyboard have blue tooth support, so they can be used for this too.
Of course, this makes it even more important to have a decent editor. I’m still going for Simplenote, which uses syncing with the cloud, but I’ve got a terrible urge to write some kind of subversion integration so that I have all my writing in the same source-controlled location.
As yet there are still some issues; for instance, the bluetooth keyboard means that the on-screen keyboard doesn’t need to be on-screen, but the wordpress app still reserves space for it.
