While iPhones and the iPod Touch aren’t considered tablets because of the small screen, the operating software and screen reader are the same in these as in the iPad, and if you’re not bothered about the screen, then they make very good – and very portable – replacements. With the addition of a small Bluetooth keyboard or a 20-cell braille display with input keys – you’ve got a machine that you can do all your email and web work on and it all fits in your handbag or coat pocket!
For low vision users of any of these devices who require the built-in magnification, using the on-screen keyboard is problematic. It is possible to use a Bluetooth keyboard with it, and an iPad dock is also available.
