Make no mistake about it: the iPad’s on-screen keyboard is actually very good. You can easily rattle off a quick email or tweet with it, and some more proficient users have been known to write several hundred words without their fingers falling off.
But not everyone gets on with it, and if you’re a professional write then you’ll probably hit its limitations. Compared to even a poor-quality physical keyboard, the iPad’s virtual one simply feels weird.
Apple’s preferred solution is for you to use the iPad with its own excellent Bluetooth keyboard. However, this means you also have to carry around something to prop the iPad up with, and although Apple’s keyboard is slim, it’s still bulky and likely to rattle around a bag. What’s more, using it on a lap (like, say, a laptop) is tricky.
