one point that i haven’t seen anyone bring up. though i operate much, much faster touch typing on a full-sized physical keyboard, once i got used to it, i actually work faster on the ipad than on a laptop’s mini-keyboard and trackpad. without the benefit of not having to look at the keyboard while i type, i find typing on either a laptop or ipad to be rather similar.
unless you can touch type on it, i don’t see how it would be worth the hassle of getting an external keyboard instead of simply familiarising yourself with the on-screen one.
i do the same on my ipad, that is, setting the browser to identify as a desktop.
