I've got an old Texas instruments speak and spell, that's what I'm using now, only a fiver from reg's range, the second hand shop down the road, I've plugged it into the Internet with a bit of old string (make sure you keep it really tight otherwise it'll all go fuzzy on you), the screen is quite small but adequate fr the cr*p I normally type out and I love the Siri feature, not that it ever answers my questions, more sort of repeats everything I type, but as I'm quite forgetful that's a bit of a bonus
