Thanks for the many suggestions. Caivano, an electronic dictionary sounds interesting, but as I already have an iPad, I'm not inclined to add another device to my arsenal! Still, I'm curious which one you use, and how it accepts handwriting -- do you have to use a stylus? Does it "talk" to you?
I think I'd be more interested in an app for the iPad. Katsuo, both of your suggestions look promising, and while the Green Goddess is pricey ($105), at least it's not as pricey as the print version. I might opt for the much less-pricey Wisdom instead, especially as it looks like it might be optimized for the iPad, and not just a blown-up (and therefore fuzzy) version of an iPod/iPhone app.
Tobberoth, thanks for the link to the yahoo page. It looks nice, but is there a J-E portion? I still need J-E at my stage. 
和英 means J-E. It's made for Japanese wanting to learn English, but it works just as well either way.
