I'm playing with an ASUS Transformer tablet, which is interesting in that it has a hardware keyboard which can be unplugged. I thought I'll post a few things about how this works in practice, from the perspective of a keyboard addict. Not the kind of thing most reviews mention, nor indeed the kind of thing most people care about.
I'll try to avoid repeating things that the average review already mentions. Beware: this article is nit-picky.
