The only dictionary that can do what you are looking for is the Canon Wordtank V80Originally Posted by WaZ
But I think you should get a zaurus. There are great dictionaries included and you can get the other ones you need for free. It is the most versitile dictionary tool ever. Not to mention you can read books, listen to music, do email, surf the net, anything you want) there is.
The sl-c3000 has 4 Gigabytes of space.
My friend got it used for 42000 yen. You can get one of the older ones for 20000 yen used. The space is good for the dictionaries though.
Not only can you use it in your hand as a pda you can also flip the screen around and type in it. It is really small so you can access it anytime if you put it in a pouch on your belt. That cannon word tank is way to big to be useful. Anytime you want to use it you would have to go digging in your bag for it which would cut down your study opportunities.
Please get the zaurus. If you need any help, send me a message. good luck
