I just bought an Apple Wireless (Bluetooth) Keyboard and am testing it with my iPad. It works fine with the iPad itself. However, there is at least one issue when using it with the WordPress for iPad app: Pressing the tab key to try to move from field to field (say Title to Tags) in the WordPress app crashes the app.
The keyboard is paired easily with the iPad. And, unlike my ancient Think Outside Bluetooth keyboard, it does not seem to need me to rekey the 6-digit pairing code every time I use the keyboard.
My guess is that Apple’s iPad keyboard dock will not work with the iPad if I leave Apple’s iPad case on (ironically). This generic Apple BT keyboard looks like a reasonable alternative. Now I need a portable stand solution that lets me prop up the iPad without removing its case.
