I don’t claim to know anything about the Arabic language (and I’m sure our readers will attest to me barely knowing the English language), but even I can tell something is very off with the new keyboard in iOS 4.2 on the iPad.
SaudiMac has posted an image of the new version of the Arabic keyboard in iOS 4.2 for the Arabic language, and then comparison shots to similar keyboards in other Apple products, and you can immediately tell the layout is different.
Most notable is that the space bar has been cut in half and replaced with a way too large button for the diacritics. Simple ergonomics tell you that the space bar needs to be longer than that and more centered.
Beyond that, the post goes on to show that Apple keeps changing the layout of the keys for the Arabic language, and the one currently on the iPad does not match up to a standard keyboard in those countries.
Considering Apple’s usual excruciating eye for details, this is somewhat surprising that they have blown this keyboard so badly. Perhaps a timely update is in order?
