Somewhere back in the mists of time we had a thread on this, but I can't find it. So ...
My trusty kuai yi tong died a couple of weeks ago and although I had another one, it didn't do what I really wanted, so this week, I bought myself a new one.
A Besta T-8000. I am having a ball with it. It does everything I loved best about my last one - handwriting capacity, voice production. But it has a ton of other stuff that is good. This one has pinyin output as well as input, character writing practice, 10 language dictionary, MP3 function, recording function to compare your own pronunciation, video upload, e-book upload capacity, and a whole lot more both in language learning functions as well as personal organiser stuff.
It doesn't come with an English manual, and so far I haven't been able to find one on line, but it does have an English help function which tells you basically what to do. (And why else do I teach English to students who are going to work as scientific translators??)
If you are looking for a good e-dic, I'd recommend this one - a bit pricey 2000Y+ even with my discount card at the Beijing Foreign Languages Bookshop - but worth it for helping with studying, and travelling.
Now all I have to do is teach it how to do the washing up and I'll be set.
